Answer:

Electrical Engineering, and, more specifically, Power Systems Engineering (or simply, Power Engineering).

Explanation:

The words high voltage and lines refer to power transmission lines (transmission of electricity). Power transmissions lines are the main concern of the electric power transmission, which is, at the same time, part of the subfield of the Electrical Engineering called Power Systems Engineering or simply Power Engineering, which "deals with the generation, transmission, distribution and utilization of electric power, and the electrical apparatus connected to such systems" Power Engineering (2020), in Wikipedia.

Then, the career that best fits this group of words is, therefore, Electrical Engineering, and, more specifically, as a subfield of it, the Power Systems Engineering.

Determine the total condensation rate of water vapor onto the front surface of a vertical plate that is 10 mm high and 1 m in th

castortr0y [4]

Answer:

Q = 63,827.5 W

Explanation:

Given:-

- The dimensions of plate A = ( 10 mm x 1 m )

- The fluid comes at T_sat , 1 atm.

- The surface temperature, T_s = 75°C

Find:-

Determine the total condensation rate of water vapor onto the front surface of a vertical plate

Solution:-

- Assuming drop-wise condensation the heat transfer coefficient for water is given by Griffith's empirical relation for T_sat = 100°C.

h = 255,310 W /m^2.K

- The rate of condensation (Q) is given by Newton's cooling law:

Q = h*As*( T_sat - Ts )

Q = (255,310)*( 0.01*1)*( 100 - 75 )

Q = 63,827.5 W

A part made from annealed AISI 1018 steel undergoes a 20 percent cold-work operation. Obtain the yield strength and ultimate str

Charra [1.4K]

Answer:

yield strength before cold work = 370 MPa

yield strength after cold work = 437.87 MPa

ultimate strength before cold work = 440 MPa

ultimate strength after cold work = 550 MPa

Explanation:

given data

AISI 1018 steel

cold work factor W = 20% = 0.20

to find out

yield strength and ultimate strength before and after the cold-work operation

solution

we know the properties of AISI 1018 steel is

yield strength σy = 370 MPa

ultimate tensile strength σu = 440 MPa

strength coefficient K = 600 MPa

strain hardness n = 0.21

so true strain is here ∈ = $ln\frac{1}{1-0.2}$ = 0.223

yield strength after cold is

yield strength = $K \varepsilon ^n$

yield strength = $600*0.223^{0.21)$

yield strength after cold work = 437.87 MPa

and

ultimate strength after cold work is

ultimate strength = $\frac{\sigma u}{1-W}$

ultimate strength = $\frac{440}{1-0.2}$

ultimate strength after cold work = 550 MPa

A meter stick can be read to the nearest millimeter and a travelling microscope can be read to the nearest 0.1 mm. Suppose you w

german

Answer: No

Explanation:

Length= 2cm= 20mm

Now meter stick can read to nearest millimeter.

It is given that length is to be measured with a precision of 1% of 20mm= 1/100 * 20= 0.2mm

Since the least count is 1mm of meter stick and precision required is less than that. So, meter stick cannot be used for this, travelling microscope can be used for this as it can read to 0.1mm.

Lesechka [4]

Answer:

Out of the four options provided

option A. actuator

is correct

Explanation:

An actuator is the only device out of the four mentioned devices that provides power and ensures the motion in it in order to manipulate the movement of the moving parts of the damper or a valve used whereas others like ratio regulator are used to regulate air or gas ratio and none mof the 3 remaining options serves the purpose
