Answer:
Anne is a mechanical engineer.
Explanation:
There are many different types of engineers <em>(mechanical, industrial, electrical, chemical and civil) </em>around the world.<em> </em>When a job involves <em>designing machines</em>, it falls under <u>mechanical engineering</u>. Such job requires a person to be as creative as possible, so he/she can come up with an innovative design that will be reasonable when used.
Designing machines includes<em> spacecraft</em>s. Therefore, Anne is a mechanical engineer working for NASA.
The performance of power plants at partial load has become a significant operational consideration for electric power grids worldwide. This technical comparison examines the range of output and the part load efficiency of combustion engines and gas turbines, and how Wärtsilä power plants deliver enhanced flexibility.
Answer:
A) 
B) 
Explanation:
Given data:
P-1 = 100 lbf/in^2
degree f
effeciency = 80%
from steady flow enerfy equation
where h1 and h2 are inlet and exit enthalpy
for P1 = 100 lbf/in^2 and T1 = 500 degree F
for P1 = 40 lbf/in^2
exit enthalapy h_2
from above equation
[1 Btu/lbm = 25037 ft^2/s^2]
b) amount of entropy
at ![h_2 = 1197.77 Btu/lbm [\tex] and [tex]P_2 = 40 lbf/in^2](https://tex.z-dn.net/?f=h_2%20%3D%201197.77%20Btu%2Flbm%20%5B%5Ctex%5D%20%20and%20%5Btex%5DP_2%20%3D%2040%20lbf%2Fin%5E2)
