A supply of nitrogen is required as an inert gas for blanketing and purging vessels. After generation, the nitrogen is compressed and stored in a bank of cylinders, at a pressure of 5 barg. The inlet pressure to the compressor is 0.5 barg, and the temperature is 20 °C. Calculate the maximum power required to compress 100 m3 /h. A single-stage reciprocating compressor will be used.
