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
