kg/s of a gas passes through a unit of 0.6 reversible steady flow. It rejects heat rate about 50 kJ/s and raises from 30m to 60m. If the velocities of the gas at inlet and outlet are 160 and 180 m/s respectively. Pressure of gas at inlet and outlet are 1.2 bar and 5.4 bar respectively. Moreover, at the entrance the internal energy is 920 kj/kg and specific volume is 1/5 m3/kg while at the exit the internal energy is 720 kj/kg and specific volume is 1/25 m3/kg .Calculate the work done during the process = The change in enthalpy * -93.6 KJ/kg O -193.6 kJ -202.4 kJ/kg
