Question

A 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

We know that

$\.{m}$ =10kg

Now

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