3. A fluid enters with a steady flow of 3.9kg/s and an initial pressure of 690 kPa, density of 3.2 kg/cu.m, velocity of 60 m/s and internal energy of 2000 kJ/kg. It leaves at 172 kPa, density of 0.64 kg/cu.m, velocity of 160 m/s and internal energy of 1950 kJ/kg. The heat loss is 18.6 kJ/kg. Determine
