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)

Answer:
required feedback resistance ( R2 ) = 100 k Ω
Explanation:
Given data :
Voltage gain = 100
input resistance ( R1 ) = 1 k ohms
calculate feedback resistance required
voltage gain of differential amplifier
= Voltage gain = R2/R1
= 100 = R2/1
hence required feedback resistance ( R2 ) = 100 k Ω
