Answer:

t₁ = 378.668 K

Explanation:

From the given information:

The heat dissipated (q) from the electrical device = \(10^4 W/m^2\)

The contact resistance between device and aluminium;

(R_{const} ) = 0.5× 10⁻⁴ m² K/W

Conductivity of aluminum (k)  = 238 \ W/mK

The thickness of aluminum plate (L) = 0.004 m

Convection coefficient (h) = 100 \ W/m^2 K

Surrounding temperature (t_2) = 278 \ k

According to Fourier's law of heat conduction.

\(q = \dfrac { t_1- t_2 }{R_{const} + \dfrac{L}{k} + \dfrac{1}{h} }\)

\(10^4 = \dfrac{t_1 - 278}{0.5 \times 10^{-4} + \dfrac{0.004}{238} + \dfrac{1}{100} }\)

\(10^4 *( 0.5 \times 10^{-4} + \dfrac{0.004}{238} + \dfrac{1}{100}) = t_1 - 278\)

\(100.668 = t_1 -278\)

t₁ = 378.668 K

(i) Types of breach of contract:  Material breach and Anticipatory breach:

(ii) Possible remedies for breach of contract Damages and Specific performance.

(i) Types of breach of contract that have occurred in this contract situation:

a) Material breach: Georgia's failure to pay the full RM200,000 upon completion of the extension constitutes a material breach of the contract. She signed an agreement promising to pay the full amount but only paid half of it.

b) Anticipatory breach: Harvey's threat to abandon the contract unless Georgia promised to pay him the full RM200,000 on completion can be seen as an anticipatory breach. By indicating his intention not to perform his obligations unless Georgia agreed to change the payment terms, Harvey breached the contract before the completion of the extension.

(ii) Possible remedies for breach of contract that can be claimed in the case:

a) Damages: Georgia may be liable to pay damages to Harvey for the breach of contract. The damages would typically be the amount necessary to put Harvey in the position he would have been in if the contract had been fully performed. In this case, it would be the remaining RM100,000 that Georgia failed to pay.

b) Specific performance: Harvey may seek a remedy of specific performance, which would require Georgia to fulfill her promise and pay the full RM200,000 upon completion of the extension. This remedy is typically sought when monetary damages would not adequately compensate the non-breaching party or when the subject matter of the contract is unique.

Answer: hL/L = 37.05/2000 ≈ 0.0185 m/m or 18.5 mm/m

Explanation:

The rate of head loss in the pipe can be determined using the Bernoulli's equation, which relates the pressure, velocity, and elevation of fluid flowing through a pipe. The Bernoulli's equation is given by:

P/ρ + V^2/2g + Z = constant

where P is the pressure, ρ is the density of the fluid, V is the velocity, g is the acceleration due to gravity, Z is the elevation, and the constant represents the total energy of the fluid.

Assuming the flow in the pipe is steady and the pipe is horizontal, the elevation term can be ignored, and the Bernoulli's equation can be simplified as:

P1/ρ + V1^2/2g = P2/ρ + V2^2/2g + hL

where P1 and V1 are the pressure and velocity at the tank, P2 and V2 are the pressure and velocity at the meter location, and hL is the head loss in the pipe.

Converting the given values to SI units:

Diameter of the pipe, d = 1,200 mm = 1.2 m

Radius of the pipe, r = d/2 = 0.6 m

Cross-sectional area of the pipe, A = πr^2 = π(0.6)^2 ≈ 1.13 m^2

Flow rate, Q = 0.126 m^3/s

Density of water, ρ = 1000 kg/m^3

Gravity, g = 9.81 m/s^2

Pressure at the tank, P1 = ρgh1, where h1 is the water surface elevation = 540 m

Pressure at the meter location, P2 = 586 kPa = 586000 Pa

Distance between the tank and meter location, L = 2 km = 2000 m

Using the continuity equation, Q = AV1, we can find the velocity of the water at the tank:

V1 = Q/A = 0.126/1.13 ≈ 0.1117 m/s

Substituting the values in the Bernoulli's equation and solving for hL:

hL = (P1 - P2)/ρg + (V2^2 - V1^2)/(2g)

= (ρgh1 - P2)/ρg + (Q^2/A^2 - V1^2)/(2g)

≈ (1000×9.81×540 - 586000)/(1000×9.81) + (0.126^2/1.13^2 - 0.1117^2)/(2×9.81)

≈ 37.05 m

Therefore, the rate of head loss in the pipe is 37.05 m over a distance of 2000 m, which gives the average rate of head loss per unit length as:

hL/L = 37.05/2000 ≈ 0.0185 m/m or 18.5 mm/m

Answer:

  C)  4.65 mA

Explanation:

The series circuit will have a voltage drop of about 0.7 V across the silicon diode, so the voltage drop across the 2 kΩ resistor is 10 -0.7 = 9.3 V. The current through the resistor is given by Ohm's Law:

  I = V/R = 9.3 V/(2 kΩ)

  I = 4.65 mA

Consequently, based on the explanations provided, Technician B is correct in asserting that the total resistance in a series circuit is the sum of all the resistances within that circuit.

Technician A and Technician B present two different statements regarding series circuits. Technician A claims that amperage is consistent at any point in a series circuit, while Technician B argues that the total resistance is the cumulative sum of all resistances in a series circuit.

According to Technician A, in a series circuit, where there is only one path for current flow, the amperage remains constant throughout the circuit. This implies that the current is identical at any point in the circuit. Thus, Technician A's statement regarding amperage in a series circuit is accurate.

Technician B's statement pertains to the total resistance in a series circuit. In this type of circuit, the total resistance is obtained by summing up all the individual resistances within the circuit. When resistors are connected in series, their resistances add up. Technician B's claim about the total resistance being the sum of all resistances in a series circuit is correct.

To determine the net power produced by the gas turbine power station, we need to calculate the work done by the turbine and the work done by the compressor. The net power produced is the difference between these two values.

The simple Brighton cycle consists of four processes:

Isentropic compression in the compressor.

Constant pressure heat addition in the combustion chamber.

Isentropic expansion in the turbine.

Constant pressure heat rejection to the surrounding environment.

Given data:

Inlet conditions:

Pressure at turbine inlet (P1) = 1 MPa

Temperature at turbine inlet (T1) = 1000 K

Exit conditions:

Pressure at turbine exit (P2) = 125 kPa

Temperature at turbine exit (T2) = 600 K

Heat expelled to the surrounding environment (Q_out) = 7922 kJ/s

Mass flow rate of air (m_dot) = 2.5 kg/s

First, let's calculate the specific enthalpy at state 1 (h1) using the air properties at the given temperature and pressure. You can refer to the air tables for this purpose.

Next, we need to calculate the specific enthalpy at state 2 (h2). We can use the temperature and pressure at state 2 and the air properties tables to determine h2.

Now, we can calculate the work done by the turbine (W_turbine) using the equation:

W_turbine = m_dot * (h1 - h2)

Since the compressor is assumed to be an isentropic process, the work done by the compressor (W_compressor) can be determined using the isentropic efficiency of the compressor (η_compressor) and the enthalpy difference between states 1 and 2:

W_compressor = (h2s - h1) / η_compressor

Where h2s is the specific enthalpy at state 2s, which can be determined using the temperature and pressure at state 2 and the air properties tables.

Finally, the net power produced (P_net) is given by:

P_net = W_turbine - W_compressor

Calculate the values using the above steps, and you will find the net power produced by the gas turbine power station.

Answer:The preferred development environment can vary depending on personal preferences, the type of project, and the programming language being used.

Explanation:

Distillation is the process of separating different components from a mixture based on their boiling points. The McCabe-Thiele method is a graphical approach used to determine the number of equilibrium stages required for distillation.

A rectification column is fed with a mixture of 50 mol % benzene and 50 mol % toluene. The feed is liquid at the boiling point and is fed into the column at a pressure of 101.32 kPa abs.The distillate is to contain 90 mol % benzene and the bottoms are to contain 10 mol % benzene.

The reflux ratio is 4.52:1. The question is asking us to find the following using the McCabe-Thiele method: kg mol/h distillate, kg mol/h bottoms, number of theoretical trays, minimum backflow rate, minimum theoretical number of plates in total backflow, and the working reflux for benzene-toluene.

The saturated vapor at the dew point refers to the liquid and vapor in equilibrium at a particular pressure. Using the Antoine equation, the dew point of the feed mixture is calculated, and from that, the relative volatility is calculated. The relative volatility is used to construct the equilibrium curve and the operating line.

The operating line intersects the equilibrium curve to determine the number of theoretical stages required. The minimum reflux ratio is found from the intersection of the q-line and the operating line. Here, we have used a feed with saturated vapor at the dew point.

The calculation for kg mol/h distillate and kg mol/h bottoms are shown below. We first need to calculate the moles of benzene and toluene in the feed and the moles of benzene in the distillate and bottoms. Let's assume the molar flow rate of the feed is F, the molar flow rate of the distillate is D, and the molar flow rate of the bottoms is B.

The mole fractions of benzene and toluene in the feed are denoted by xB and xT, respectively, and the mole fraction of benzene in the distillate and bottoms are denoted by yD and yB, respectively.

Therefore:

F = 100 kg mol/hxB = 0.5xT = 0.5yD = 0.9yB = 0.1

Moles of benzene in feed

= 0.5 × 100 = 50 kmol/h

Moles of toluene in feed

= 0.5 × 100 = 50 kmol/h

Moles of benzene in distillate

= 0.9D kmol/h

Moles of benzene in bottoms

= 0.1B kmol/h

We know that the total flow rate of the feed = F, which is equal to the total flow rate of the distillate and the bottoms. Therefore,

F = D + BOr100 = D + BTo

solve for D and B, we need to use the reflux ratio.

Explanation:

The Remaining Bulbs will either burn more brightly ( draw more current ) or Burn less brightly ( draw less current).and this depends on the arrangement of the light bulbs in the various circuit.

If the light bulbs are connected in series the remaining bulbs will burn out as soon as  any light bulb burns out and this is because bulbs connected in series receive the same amount of current ,

If the light bulbs are connected in parallel the remaining bulbs will not burn out because each bulb receives current based on its resistance.

Answer:

the process capability index for the precision machining process is 0.667

Explanation:

Given the data in the question;

Lower Specification Limits LSL = 0.99 mm

Upper Specification Limits USL = 1.01 mm.

The standard deviation σ = 0.005 mm

mean μ = 1 mm

capability index Cpk = ?

Cpk = min( USL - μ / 3σ, μ - LSL / 3σ )

we substitute

Cpk = min( 1.01 mm - 1 mm / 3(0.005 mm ), 1 - 0.99 mm / 3(0.005 mm) )

Cpk = min( 0.01 mm / 0.015 mm, 0.01 mm / 0.015 mm )

Cpk = min( 0.6666, 0.6666 )

∴ Cpk = 0.6666 ≈ 0.667

Therefore, the process capability index for the precision machining process is 0.667
