A steady flow system receives 1 kg/s of a substance with u1 = 1000 kJ/kg, P1 = 500 kPa, v1 = 1.2 m3 /kg, and v1 = 50m/s. There is a heat loss of 1000 kJ/kg, and the fluid exits at v2 = 150 m/s, v2 = 0.8 m3 /kg, P2 = 100 kPa and h2 = 1000 kJ/kg. Determine the power and the exit specific internal energy.
