0.8 kg of air flows through a compressor under steady state conditions. The properties of air at entry are : pressure 1 bar, velocity 10 m/s, specific volume 0.95 m3/kg and internal energy 30 kJ/kg. The corresponding values at exit are 8 bar, 6 m/s, 0.2 m3/kg and 124 kJ/kg. Neglecting change in potential energy, the power input will be

• A. 117 kW
• B. 127 kW
• C. 137 kW
• D. 147 kW
