In a steady flow apparatus, a fluid enters with a specific volume of 0.40m³/kg, a pressure of 550 kPa and a velocity of 20 m/s. The inlet port is 40 m above the floor and the outlet port is at the floor level. The fluid exits with a specific volume of 0.82m2/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?
