8. In a steady flow apparatus 135 KJ of work is done by each kg of fluid. The specific volume of the fluid, pressure, and speed at the inlet are 0.30 m³/kg, 600 kPa, and 16m/s. The inlet is 32m above the floor and the discharge pipe are at floor level. The discharge conditions are 0.60 m³/kg, 1 bar, and 270 m/s. The total heat loss between the inlet and discharge is 9KJ/kg of fluid. In flowing through this apparatus, does the specific internal energy increase or decrease? And by how much?
