In a steady flow apparatus, 250 kJ of work is done by each kg of the fluid. The specific volume of the fluid, pressure and speed at the inlet are 0.37 m³ /kg, 600 kPa and 16 m/s. The inlet is 32 m above the floor and the discharge pipe is at floor level. The discharge conditions are 0.62 m³ /kg, 100 kPa and 270 m/s. The internal energy decreases from 100 kJ/kg to 50 kJ /kg. How much heat in kJ/kg is added to the system?
