In a steady flow apparatus, 135 kJ of work is done by each kgm of 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/kgm, 100 kPa, and 270 m/s. The total heat loss between the inlet and discharge is 9 kJ/kgm of fluid. In flowing through this apparatus, does the specific internal energy increase or decrease and by how much?
