Saturated vapor steam at 5 Psia eneters an adiabatic heat exchanger and leaves as saturated liquid at 5 psia. The steam flow rate is 5 lbm/s.
A) Calculate the heat lost by the steam in Btu/s
B) if cooling is to be accomplished by cooling water and the cooling water temperature gain is to be 15 F, calculate the mass flow rate of the cooling water required in lbm/s.
