(OP)
i need a solution of this question
for an air standard cycle atmospheric air is at 27C it is compressed to the high pressure and then cooled to 30C . the turbine exhausts air at 7 C the air leaving the space is at 11 C if the space is 17 KW determine 1-air flow rate ,2-motor power ,3-high pressure, 4- C.O.P
i dont know if am i right
Q= m cp (T4-T1)
m =17/(1.005(16))
p1=101kpa (P2/P1)^(n/n-1)=(T2/T1)
n=1.4
i dont know T2 i cannot complete.
thanks all
