In a steady flow apparatus, a fluid enters with a specific volume of 0.40 m3/kg, a pressure of 550 kPa and a velocity of 20 m/s. The inlet port is 40m above the floor and the outlet port is at the floor level. The fluid exists with a specific volume of 0.82 m3/kg, a pressure of 100 kPa and a velocity of 280 m/s. The apparatus produces 140 kJ of work per kg of fluid and a 12 kJ/kg of heat loss occurs between the inlet and outlet ports. Determine the amount of change in internal energy in the apparatus. Is the internal energy increases or decreases?

volume of 0.40 m3/kg, a pressure of 550 kPa and a velocity
of 20 m/s. The inlet port is 40m above the floor and the
outlet port is at the floor level. The fluid exists with a
specific volume of 0.82 m3/kg, a pressure of 100 kPa and a
velocity of 280 m/s. The apparatus produces 140 kJ of

between the inlet and outlet ports. Determine the amount
of change in internal energy in the apparatus. Is the internal
energy increases or decreases?
