c. 2324.86 KJ/kg
d. 0.25539 --- 25.5%
e. 3980.63 KJ/kg
Explanation:
Given:-
Condenser exit parameters:
P1 = 50 KPa , saturated liquid
Boiler exit / Turbine exit parameters:
P3 = 2 MPa
T3 = 1100°C
Solution:-
- Adiabatic and reversible processes for pump and turbine are to be applied
- Assume changes in elevation heads within the turbomachinery to be negligible.
- Assume steady state conditions for fluid flow and the use of property tables will be employed.
Isentropic compression of water in pump:
Pump inlet conditions : Pump exit to Boiler pressure:
P1 = 50 KPa, sat liquid P2 = P3 = 2 MPa
h1 = 340.54 KJ/kg s2 = s1 = 1.0912 KJ/kg.K
s1 = 1.0912 KJ/kg.K h2 = 908.47 KJ/kg
- Apply energy balance for the pump and determine the work input ( Win ) required by the pump:
Win = h2 - h1
Win = 908.47 - 340.54
Win = 567.93 KJ/kg
Isentropic expansion of steam in turbine:
Turbine inlet conditions : Turbine exit to condenser pressure:
P3 = 2MPa, T3 = 1100°C P4 = P1 = 50 kPa
h3 = 4889.1 KJ/kg s4 = s3 = 8.7842 KJ/kg.K .. superheated
s3 = 8.7842 KJ/kg.K h4 = hg = 2665.4 KJ/kg
- Apply energy balance for the turbine and determine the work output ( Wout ) produced by the turbine:
Wout = h3 - h4
Wout = 4889.1 - 2665.4
Wout = 2223.7 KJ/kg
- The net work-output obtained from the cycle ( W-net ) is governed by the isentropic processes of pump and turbine.
W_net = Wout - Win
W_net = 2223.7 - 567.93
W_net = 1655.77 KJ/kg ... Answer
- The fraction of work generated by turbine is used to operate the pump. The a portion of Wout is used to drive the motor of the pump. The pump draws ( Win ) amount of work from pump. The ratio of work extracted from turbine ( n ) would be:
n = Win / Wout
n = 567.93 / 2223.7
n = 0.25539 ... Answer ( 25.5 % ) of work is used by pump
- The amount of heat loss in the condenser ( consider reversible process ). Apply heat balance for the condenser, using turbine exit and condenser exit conditions:
Ql = h4 - h1
Ql = 2665.4 - 340.54
Ql = 2324.86 KJ/kg ... Answer
- The amount of heat gained by pressurized water in boiler ( consider reversible process ). Apply heat balance for the boiler, using pump exit and boiler exit conditions:
Qh = h3 - h2
Qh = 4889.1 - 908.47
Qh = 3980.63 KJ/kg ... Answer

M3.10. Find Current If I_1 = 40 mA, R_4 = 1 kΩ, R_5 = 7 kΩ, R_6 = 4 kΩ, R_7 = 7 kΩ, R_8 = 1 kΩ. The values of resistors R_2 and R_3 are unknown. Using a voltmeter, it is found that V_5 = 28 V across R_5. Find the current, I_6, flowing through R_6.
The objective is to find the current flowing through resistor R_6 (I_6), given the values of resistors R_4, R_5, R_6, R_7, and R_8, as well as the current flowing through resistor R_1 (I_1) and the voltage across resistor R_5 (V_5).
To find the current flowing through resistor R_6, we need to use Kirchhoff's Current Law (KCL) to solve for the unknown currents in the circuit. First, we can use Ohm's Law to find the voltage across resistor R_7, which is equal to V_7 = I_1 * R_7. Next, we can use KCL to find the total current flowing into node A, which is equal to I_A = I_1 + I_3, where I_3 is the current flowing through resistors R_2 and R_3. Since the values of resistors R_2 and R_3 are unknown, we can use the voltage across resistor R_5 and the known resistances to find the current flowing through resistor R_5, which is equal to I_5 = V_5 / R_5. Using KCL again, we can find the current flowing through resistor R_4, which is equal to I_4 = I_A - I_5. Finally, we can use Ohm's Law to find the voltage across resistor R_6, which is equal to V_6 = I_6 * R_6. Using KCL one last time, we can find the current flowing through resistor R_6, which is equal to I_6 = (V_7 - V_6) / R_8.
To summarize, the current flowing through resistor R_6 can be found by using Kirchhoff's Current Law and Ohm's Law to solve for the unknown currents and voltages in the circuit. The final equation for the current flowing through resistor R_6 is I_6 = (V_7 - V_6) / R_8.

a. When we want to create defined groups from a continuous feature
b. When we want to transform categorical features into continuous features
c. When we want to remove low-quality features
d. When we want to create a new feature by combining existing ones
The appropriate feature engineering step for binning would be:
a. When we want to create defined groups from a continuous feature.
Binning is a useful technique in feature engineering when we want to convert a continuous feature into discrete or categorical groups. It involves dividing the range of values of a continuous feature into bins or intervals and assigning each value to a corresponding bin. This allows us to create defined groups or categories based on the values of the continuous feature.
Binning can be beneficial in various scenarios. For instance, it can help simplify complex data patterns, handle outliers or noise, and capture non-linear relationships between the feature and the target variable. Binning can also be used to address issues related to model complexity, data sparsity, or limited sample sizes.
By transforming a continuous feature into discrete groups, binning can enable models to capture patterns and make predictions based on the created categories. It allows for a more interpretable representation of the data and can improve the performance of certain machine learning algorithms, especially those that work better with categorical or ordinal data.
In summary, binning is an appropriate feature engineering step when we want to create defined groups or categories from a continuous feature. It can help simplify complex data patterns, handle outliers, and capture non-linear relationships, ultimately enhancing the modeling and prediction capabilities of machine learning algorithms.

A single-threaded 25-mm power screw hasa pitch of 5 mm. The frictional diameter of the collar is 45 mm. The max load onvertical direction of the screw is5kN. The collar has a coefficients of friction of0.06, and he threads hasa coefficients of friction of0.09. Find the overall efficiency and the torque to "raise" and "lower" the load.
Answer:
torque to raise the load = 16.411 Nm
torque to lower the load = 8.40 Nm
overall efficiency = 0.24
Explanation:
Given:
max load on vertical direction of the screw = Force = F = 5kN
frictional diameter of the collar = 45 mm
Diameter = 25 mm
length of pitch = 5 mm
coefficient of friction for thread µ = 0.09
coefficient of friction for collar µ\(_{c}\) = 0.06
To find:
torque to "raise" the load
torque to and "lower"
overall efficiency
Solution:
Compute torque to raise the load:
\(T_{R} = \frac{ Fd_{m}}{2} (\frac{L+(\pi ud_{m}) }{\pi d_{m}-uL }) +\frac{Fu_{c} d_{c} }{2}\)
where
\(T_{R}\) is the torque
F is the load
\(d_{m}\) is diameter of thread
\(d_{c}\) is diameter of collar
L is the thread pitch distance
µ is coefficient of friction for thread
µ\(_{c}\) is coefficient of friction for collar
Putting the values in above formula:
\(T_{R}\) = 5(25) / 2 [5+ (π(0.09)(25) / π(25)-0.09(5)] + 5(0.06)(45) / 2
= 125/2 [5 + (3.14)(0.09)(25)/ 3.14(25)-0.45] + 13.5/2
= 62.5 [(5 + 7.065) / 78.5 - 0.45] + 6.75
= 62.5 [12.065 / 78.05 ] + 6.75
= 62.5 (0.15458) + 6.75
= 9.66125 + 6.75
= 16.41125
\(T_{R}\) = 16.411 Nm
Compute torque to lower the load:
\(T_{L} = \frac{ Fd_{m}}{2} (\frac{(\pi ud_{m}) - L }{\pi d_{m}-uL }) +\frac{Fu_{c} d_{c} }{2}\)
= 5(25) / 2 [ (π(0.09)(25) - L / π(25)-0.09(5) ] + 5(0.06)(45) / 2
= 125/2 [ ((3.14)(0.09)(25) - 5) / 3.14(25)-0.45 ] + 13.5/2
= 62.5 [ (7.065 - 5) / 78.5 - 0.45 ] + 6.75
= 62.5 [ 2.065 / 78.05 ] + 6.75
= 62.5 (0.026457) + 6.75
= 1.6535625 + 6.75
= 8.40 Nm
Since the torque required to lower the the load is positive indicating that an effort is applied to lower the load, Hence the thread is self locking.
Compute overall efficiency:
overall efficiency = F(L) / 2π \(T_{R}\)
= 5(5) / 2(3.14)( 16.411)
= 25/ 103.06108
overall efficiency = 0.24

sin x +√3 coax= √2
Answer:
The two values of x are 2n*pi + pi/12 and 2n*pi -5pi/12
Explanation:
The given equation is
Sin x +√3 Cosx= √2
Upon dividing the equation by 2 we get
\(\frac{1}{2}Sinx + \frac{\sqrt{3} }{2}Cosx = \frac{\sqrt{2} }{2}\)
Sin(\(\frac{pi}{6}\))*Sinx + Cos(\(\frac{pi}{6}\))*Cosx = \(\frac{1}{\sqrt{2} }\)
This makes the formula of
CosACosB + SinASinB = Cos(A-B)
Cos(x-\(\frac{pi}{6}\)) = \(\frac{1}{\sqrt{2} }\)
cos(x- pi/6) = cos(pi/4)
upon writing the general equation we get
x-pi/6 = 2n*pi ± pi/4
x = 2n*pi ± pi/4 -pi/6
so we will have two solutions
x = 2n*pi + pi/4 -pi/6
= 2n*pi + pi/12
and
x = 2n*pi - pi/4 -pi/6
= 2n*pi -5pi/12
Therefore the two values of x are 2n*pi + pi/12 and 2n*pi -5pi/12.
The gravitational force exerted on a solid object is 5N. When the object is suspended from a spring scale and submerged in water, the scale reads 3.50 N. Find the density of the object.
The density of the object is 3333.33 kg/m³. The density of an object is a measure of how heavy it is for a given size, i.e. the mass of material per unit volume.
What is gravitational force?Gravity, also known as gravitational force, pulls objects with mass toward each other. We frequently consider the force of gravity from Earth. This force is responsible for keeping your body on the ground. Any object with mass, on the other hand, exerts a gravitational force on all other objects with mass.
Calculation of density of object?Density: This can be defined as the ratio of the mass of a body to its volume.
The unit of density is kg/m³.
From Archimedes principle,
R.d = W/U = D/D'
Where R.d = relative density, W = weight of the object in air, u = upthrust in water, D = Density of the object, D' = Density of water.
W/U = D/D'
making D the subject of the equation
D = D'(W/U).......................... Equation 1
Given: W = 5.0 N, U = 5.0 -3.5 = 1.5 N, D' = 1000 kg/m³
U = lost in weight = weight in air - weight in water
Substitute into equation 1
D = 1000(5/1.5)
D = 3333.33 kg/m³
Thus the density of the object = 3333.33 kg/m³

Describe the role of nadh and fadh2 in production of atp for biologic work. is this reaction directly coupled from initial substrates?
NADH and FADH2 are two electron carriers that are used in the electron transport chain of cellular respiration to produce ATP.
These molecules play a critical role in the production of ATP by transferring electrons to the electron transport chain to generate an electrochemical gradient.
The gradient is then used to drive the phosphorylation of ADP to ATP by ATP synthase.
The role of NADH and FADH2 in the production of ATP for biological work is described in more than 100 words below.
NADH and FADH2 are the two electron carriers that are used in the electron transport chain of cellular respiration to produce ATP.
They both play critical roles in the process of ATP production.
NADH carries electrons to the electron transport chain through its association with the enzyme complex NADH dehydrogenase.
This electron transport chain is responsible for the formation of a proton gradient across the inner mitochondrial membrane.
Both NADH and FADH2 are critical to the production of ATP in biological systems, as they provide the electrons that are necessary to drive the electron transport chain.
Without these electron carriers, the electrochemical gradient would not be established, and the phosphorylation of ADP to ATP would not occur.
This reaction is directly coupled from initial substrates because the ATP production process is tightly regulated and dependent on the electron transport chain's functioning.
In summary, NADH and FADH2 play critical roles in the production of ATP for biological work by transferring electrons to the electron transport chain,
which drives the phosphorylation of ADP to ATP by ATP synthase.

An electric motor runs at 600 r/min when driving a load requiring a torque of 200 N m. Ifthe motor input is 15 kW, calculate the efficiency of the motor and the heat lost by the motor perminute, assuming its temperature to remain constant
The efficiency of the motor is 80%.
The heat lost by the motor per minute is 7.5 kW.
Here are the calculations:The output power of the motor is given by:
P_o = τ * ω
where τ is the torque and ω is the angular velocity.
P_o = 200 N m * (2π * 600 r/min) / 60 s/min = 6000 W
The efficiency of the motor is given by:
η = P_o / P_i
where P_i is the input power.
η = 6000 W / 15 kW = 0.8
The heat lost by the motor per minute is given by:
Q = P_i - P_o
Q = 15 kW - 6000 W = 7.5 kW

How many flip-flop values are complemented in an 8-bit binary ripple counter to reach the next count value after: 0110111 and 01010110?
Answer:
- Four (4) flip-flop values will complemented
- one (1) flip-flop value will complemented
Explanation:
To find how many flip flop number of bits complemented, we just need to figure out what the next count in the sequence is and find how many bits have changed.
taking a look at the a) 00110111
we need to just 1 to the value,
so
00110111 + 0000001 = 00111000
So here, only the first four bits are complemented.
Therefore Four (4) flip-flop values will complemented
Next
b) 01010110
we also add 1 to the value
01010110 + 00000001 = 01010111
only the first bit is complemented.
Therefore one (1) flip-flop value will complemented
