The rate of cooled water flow in lbm/hr is 244100 lbm/hr.

We need to know about the mass rate to solve this problem. The rate of cooled water will be the same as the rate of water enters the tower minus by the wet water releasing to the air.

m' cooled water = m'water - m'released

From the question above, the given parameters are

m' water = 250000 lbm/hr

m'dry air = 151000 lbm/hr

m' wet air = 156900 lbm/hr

Find the rate of water released to the air

m'released = m'wet air - m'dryair

m'released = 156900 - 151000

m' released = 5900 lbm/hr

Calculate the rate of cooled water flow

m' cooled water = m'water - m'released

m' cooled water = 250000 - 5900

m' cooled water = 244100 lbm/hr

Hence, the rate of cooled water flow in lbm/hr is 244100 lbm/hr.

An estimate of the safety factor of the shaft is 1.10

We have the following:

Torque=230nm

Diameter=25mm

Yield tension=160mpa

Yield compression=170mpa

To estimate the safety factor of the shaft, we will have to find first the following:

Maximum shear stress:

Shear stress=[tex]\frac{16T}{\pi d^{3} }[/tex]

                   =    [tex]\frac{16*230}{\pi *(25mm*\frac{10^{-3}m }{1mm})^{3} }[/tex]

                   =75MPa

We, now get the principle stress:

σ[tex]_{1}[/tex]=75MPa

σ[tex]_{2}[/tex]=-75MPa

The torsional yield strength:

Torsional yield strength=(yield strength in tension*yield strength in compression)/(yield strength in tension +yield strength in compression)

                                   =(160*170)/(160+170)

                                  =82.4MPa

Now, we can calculate the factor of safety using this given relation:

Factor of safety=(Torsional yield strength/Maximum shear stress)

                         =82.4MPa/75MPa

                         =1.0987

                         =1.10

A performance (HC) curve for a given centrifugal pump shows that option B. Flow rate decreases as the head required to overcome system resistance increases.

The Centrifugal pump curves are helpful because they display metrics for the performance of the pump based on the head (pressure) the pump produces and the water flow through the pump. Impeller diameter, head, as well as the pump speed all affect flow rates.

Note that an instrument that predicts a pump's head and flow performance is a centrifugal pump performance curve. Pumps provide low volume flow rates when pumping against high-pressure heads and high volume flow rates if they are said to be pumping against low-pressure heads.

Therefore, one can say that every centrifugal pump has a curve that it follows in order to function, and every curve has a start point (the shut-off or zero flow) and an end point (the end-of-curve or the maximum flow that can be achieved without overtaxing the motor).

If Enzo’s balance sheet for the month of July is has both assets and liabilities. The expression that will finds Enzo’s net worth is: A. 127,100 dollars minus 88,500 dollars .

Net worth can be determine by deducting the assets of a company by its liabilities which in turn implies that a company or an organization will tend to known their net worth after deducting their financial obligation (debt) from their assets .

Using this formula to find the net worth

Net worth = Assets -Liabilities

Where :

Assets = $127,100

Liabilities = $88,500

Let plug in the formula

Net worth = $127,100 -$88,500

Net worth = $38,600

Hence,

127,100 dollars minus 88,500 dollars .

= $38,600

Answer:

divide 3.8 by 0.4 you get 9.5 which is 9 1/2 in a fraction

The line to line voltage is 4160. The real power loss is 12 Kva , the reactive power loss is 81 Kvar. The total real power supplies is 540 kVa. The total reactive power supplied at the end of line is  (540 + 477j)

The first calculation is the  per phase line to node voltage.

= 2200√3 / √3

= 2200 V

Next is three-phase complex power absorbed by load 1

560 x 10³ ∠cos-1(0.707)

= 560 x 10³∠45

Then we would have

(396 + j396)kva

We have S2 = 132kva

next is the total complex load calculation

(396 + j396 + 132)kva

= 528 + j396 kva

= 660 ∠36.87 degrees kva

total current that is in the line

= 660 x 10³ ∠-36.87 / 3 x 2200

= 100 ∠ -36.87 degrees kva

Using the voltage law of Kirchoff

E1 = E2 + ZLI

= (2200 + 0.4 + j2.7)100 ∠ -36.87

= 2200 ∠0 + (2.73 ∠ 81.57)(100 ∠ -36.87)

=2401∠4.5 degrees

√3 x 2401

= 4160

b. Total real and reactive loss

= 3 x (.4 + 2.7j)(100 x100)

= 30x10^3)(.4 + 2.7j)

= 12 + 81 j

find the real power loss

p = 12 kw

total power loss is 12 kw

The reactive power loss is 81 Kvar

c. total 3 phase power

2401.7∠4.58 and 100∠36.87

= 3(2401.7∠4.58  x  100∠36.87)

= (540 + 477j)

the total real power is 540 kW

The total complex power of load and line

The location at which a fuse should be installed in the 120 V, 20 A, residential circuit is in the live wire on the circuit, not in the neutral wire. The correct option is therefore;

A. A fuse should never be installed in the neutral.

The function of an electric fuse, which is a safety device, is to provide protection from an over flow of current in the circuit.

Generally, an electric fuse consists of a metal wire or filament that melts, due to its rise in temperature when excessive current or current at an unsafe level flows in the circuit, thereby opening the circuit, to protect the circuit and its components.

The effect of excessive or over current in a circuit is that it causes the circuit component to heat up and burn, such that the circuit and device stops functioning, and in some cases, may cause a fire.

The fuse, which is a circuit safety device, should be the first contact of the current.
