at what rate is the flywheel spinning when the power comes back on?

we have to calculate the strength coefficient (K) and strain hardening exponent (n) representing a power law true stress/strain curve (σ=Kɛⁿ).To determine the strength coefficient (K), we have to take the antilogarithm of the intercept of the fitted curve (log σ = n log ɛ + log K) of a true stress-true strain curve, which is obtained from the plotted data.

The strain hardening exponent (n) is the slope of the fitted curve log σ = n log ɛ + log K. In other words, it is the slope of the graph plotted between the true stress (σ) and the true strain (ɛ) taken in logarithmic scales.Using the experimental data above, we can calculate the strength coefficient (K) and strain hardening exponent (n) as follows:It can be seen that the slope of the graph plotted between the true stress (σ) and the true strain (ɛ) is given by the slope of the line joining the points on the curve. Using two points (0.06, 169) and (0.5, 488), we can obtain the slope:Thus, the strain hardening exponent (n) is 0.44 (approximately).

The strength coefficient (K) is calculated as the antilogarithm of the y-intercept of the straight line.Using the values of n and intercept from above, we have:K = 69.0/0.06⁰.⁵⁷= 408.74Thus, the strength coefficient (K) and strain hardening exponent (n) representing a power law true stress/strain curve (σ=Kɛⁿ) are approximately 408.74 MPa and 0.44 respectively.

(a) The time constant of the circuit can be calculated as:

τ = L/R = 4/10 = 0.4 seconds

At t = τln(2), the current will have reached 50% of its final steady value. Therefore:

t = τln(2) = 0.4ln(2) ≈ 0.277 seconds

(b) The current in the circuit can be calculated using the formula:

i(t) = (V/R)(1 - e^(-t/τ))

At t = 0.5 seconds, we have:

i(0.5) = (20/10)(1 - e^(-0.5/0.4))

≈ 1.98 amps

Therefore, the value of the current after 0.5 seconds is approximately 1.98 amps.

Answer:

The power cost savings for the 8 inches pipe offsets the increased cost for the pipe therefore to save costs the 8-inch pipe should be used

Explanation:

The given parameters in the question are;

The distance of the river from the the site, d = 2,500 ft.

The planned flow rate = 600 gal/min

The diameter of the pipe, d = 6-in.

The pipe material = Steel

The cost of pumping = 3 cents per kilowatt-hour

The Bernoulli's equation is presented as follows;

\(\dfrac{P_a}{\rho} + g\cdot Z_a + \dfrac{V^2_a}{2} + \eta\cdot W_p = \dfrac{P_b}{\rho} + g\cdot Z_b + \dfrac{V^2_b}{2} +h_f +W_m\)

\({P_a} = {P_b} = Atmospheric \ pressure\)

\(Z_a = Z_b\)

Vₐ - 0 m/s (The river is taken as an infinite source)

\(W_m\) = 0

The head loss in 6 inches steel pipe of at flow rate of 600 gal/min = 1.19 psi/100 ft

Therefore; \(h_f\) = 1.19 × 2500/100 = 29.75 psi

\(\eta\cdot W_p = \dfrac{V^2_b}{2} +h_f\)

\(V_b\) = Q/\(A_b\) = 600 gal/min/(π·(6 in.)²/4) = 6.80829479 ft./s

\(V_b\) ≈ 6.81 ft./s

The pressure of the pump = P =  62.4 lb/ft³× (6.81 ft./s)²/2 + 29.75 psi ≈ 30.06 psi

The power of the pump = Q·P ≈ 30.06 psi × 600 gal/min = 7,845.50835 W

The power consumed per hour = 7,845.50835  × 60  × 60 W

The cost = 28,243.8301 kW × 3  = $847.31  per hour

Annual cost =  $847.31 × 8766 = $7,427,519.46

Pipe  cost = $15/ft × 2,500 ft = $37,500

Annual charges = 20% × Installed cost = 0.2 × $37,500 = $7,500

Total cost = $37,500 + $7,500 + $7,427,519.46 = $7,475,519.46

For the 8-in pipe, we have;

\(V_b\) = Q/\(A_b\) = 600 gal/min/(π·(8 in.)²/4) = 3.83 ft./s

\(h_f\) = 1.17 ft/100 feet

Total head loss = (2,500 ft/100 ft) × 1.17 ft. = 29.25 ft.

\(h_p = \dfrac{V^2_b}{2 \cdot g} +h_f\)

∴ \(h_p\) = (3.83 ft./s)²/(2 × 32.1740 ft/s²) + 29.25 ft. ≈ 29.5 ft.

The power of the pump = ρ·g·h × Q

Power of pump = 62.4 lb/ft³ × 32.1740 ft/s² × 29.5 ft.× 600 gal/min = 3,363.8047 W

The cost power consumed per annum = 3,363.8047 W × 60 × 60 × 3 × 8766 = $3,184,608.1

The Cost of the pipe = $20/ft × 2,500 ft. = $50,000

The total cost plus charges = $3,184,608.1 + $50,000 + $10,000 = $3,244,608.1

Therefore it is more affordable to use the 8-in pipe which provides substantial savings in power costs

a. The equal-frequency partitioning for the given sales price records would be as follows: Bin 1: 5, 10, 11, 13  Bin 2: 15, 35, 50, 55  Bin 3: 72, 92, 204, 215

(a) Equal-Frequency (Equidepth) Partitioning:

Equal-frequency partitioning divides the data into bins of equal frequency. In this case, we have 12 records, so we need to partition them into three bins.

Now, we can assign the records to the bins based on their order. Starting from the lowest value, we assign four records to each bin until all records are assigned. If there are any remaining records, we distribute them evenly across the bins.

Using this method, the equal-frequency partitioning for the given sales price records would be as follows:

Bin 1: 5, 10, 11, 13

Bin 2: 15, 35, 50, 55

Bin 3: 72, 92, 204, 215

(b) Equal-Width Partitioning:

Equal-width partitioning divides the data into bins of equal width or range. In this case, we need to determine the range of the data and then divide it into three equal-width bins.

The range of the data is the difference between the maximum and minimum values, which is 215 - 5 = 210.

Each bin will have a width of 210 / 3 = 70. Starting from the minimum value, we assign the records to the bins based on their value falling within the corresponding width range.

Using this method, the equal-width partitioning for the given sales price records would be as follows:

Bin 1: 5, 10, 11, 13, 15, 35

Question:

In the given circuit, V(t)=12cos(2000t+45)V, R1=R2=2Ω, L1=L2=L3=3mH and C1=250μF. You are required to find the Thevenin equivalent of this circuit using phasors.

a. If you write the Thevenin voltage, Vth, in phasor form, what is the magnitude of this phasor? Put your answer in the box below without units.

b. What is the value of the angle associated with the phasor Vth, in degrees?

c. Now, calculate the Thevenin impedance, Zth. What is the magnitude of this phasor?

d. What is the angle associated with the phasor Zth, in degrees?

Answer:

Vth = 6 < 45° V

Zth = 1.414 < 45°

a. The magnitude of the Thevenin voltage is 6 V

b. The phase angle of the Thevenin voltage is 45°

c. The magnitude of the Thevenin impedance is 1.414 V

d. The phase angle of the Thevenin impedance is 45°

Explanation:

The given voltage is

V(t)=12cos(2000t+45)

In phasor form,

V(t) = 12 < 45° V

So the magnitude of voltage is 12 V and the phase angle is 45°

Also the frequency ω = 2000

then the inductance is

L₁ = L₂ = L₃ = jωL = j×2000×0.003 = j6 Ω

and the capacitance is

C₁ = 1/jωC = 1/(j×2000×250x10⁻⁶) = -j2 Ω

and the resistance is

R₁ = R₂ = 2 Ω

Thevenin voltage:

The Thevenin voltage is the voltage that appears across the open-circuited terminals a-b (after removing L₃)

The Thevenin voltage is given by

Vth = V(t) × [ (R₂ + L₂) / (R₁ + L₁) + (R₂ + L₂) ]

Please note that there is no current flow in the capacitor due to open-circuited terminal a-b

Vth = 12 < 45°  × [ (2 + j6) / (2 + j6) + (2 + j6) ]

Vth = 12 < 45°  × [ (2 + j6) / (4 + j12) ]

Vth = 4.24264 + j4.24264 V

In phasor form,

Vth = 6 < 45° V

a. The magnitude of the Thevenin voltage is 6 V

b. The phase angle of the Thevenin voltage is 45°

Thevenin Impedance:

The Thevenin Impedance is the impedance of the circuit calculated when looking from the terminal a-b

Zth = [ (R₁ + L₁) × (R₂ + L₂) / (R₁ + L₁) + (R₂ + L₂) ] + (-j2)

Zth = [ (2 + j6) × (2 + j6) / (2 + j6) + (2 + j6) ] - j2

Zth = [ (2 + j6) × (2 + j6) / (2 + j6) + (2 + j6) ] - j2

Zth = [ (-32 + j24) / (4 + j12) ] -j2

Zth = [ (1 +j3) ] - j2

Zth = 1 + j Ω

In phasor form,

Zth = 1.414 < 45°

c. The magnitude of the Thevenin impedance is 1.414 V

d. The phase angle of the Thevenin impedance is 45°

Answer:

It is economical

Explanation:

Given data for determining

cost of product = £5 per kg

cost of solvent = £20 per /kg

additional solvent makeup = 10 kg/d

current loss of product = 0.7 kg/h

anticipated recovery of product = 80%

additional service ( utility cost ) = negligible

Determine if it is economical to install the recovery system

cost of product = £5 per kg

cost of solvent = £20 per /kg

additional solvent required = 10 kg / d

cost of additional solvent in a day  = £200 / day  ( £20 per kg * 10 kg / d )

product lost = 0.7 kg/h

product recovered = 0.7 * 80% = 0.56 kg/h

therefore product recovered in a day = 0.56 * 24 = 13.44 kg / day

Next :

calculate income generated from product recovery

13.44 kg/day *  £20 /kg =  £268.88 / day

Determine if it is economical

Income - cost

= £268.88 - £200

=  £68.88  ( hence it is economical )

A triangular plate with a base 5 ft and altitude 3 ft is submerged vertically in water  so that the top is 4 ft below the surface. If the base is in the surface of water, find the force against onr side of the plate. Express the hydrostatic force against one side of the plate as an integral and evaluate it. (Recall that the weight density of water is 62.5 lb/ft3.)

Let "x" be the side length submerged in water.

Then

w(x)/base = (4+3-x)/altitude

w(x)/5 = (4+3-x)/3

w(x) = 5* (7-x)/3

Hydrostatic force = 62.5 integration of  x * 4 * (10-x)/3 with limits from 4 to 7

HF = integration of 40x - 4x^2/3

HF = 20x^2 - 4x^3/9 with limit 4 to 7

HF = (20*7^2 - 4*7^(3/9))- (20*4^2 - 4*4^(3/9))
