Question

work done on the steady flow system is 30 kJ/kgm. Calculate the heat in HP 

if the mass flow rate of fluid is 10 kg per minute given that the internal energy 

is decreased by 10 kJ/kgm and the fluid flow is increased by 20 kJ/kgm. Also, 

identify if the heat is added to the system or rejected by the system

Answer 1

$W=\frac {\dot m}{746}(U+A-P)=27~ hp$ >0, added.
