Hydrogen gas p1=15 psia, t1= 80 degree f. compressed at a rate of 20 ft3/min in a hot environment until p2= 75.3 psig. heat is introduced at a rate of 20 btu/min and the change in entropy is 0.268 btu/min-r.

t1= 540r, h1= 3660.9, u1=2588.5, sp. heat = 31.232

(a) what is final t in r?

(b) what is the work equivalent hp if the system is non flow?

(c) work if the system is steady flow in btu/min?
