Hydrogen (MW=2) at 1.2 atm pressure abs and at 300K is sent to an isothermal compressor and is compressed to 4.8 atm abs at the compressor and sent from the compressor into a horizontal pipe 50 mm in diameter and 5 km in Jeusth. The pressure at the pipe outlet is measured as 1 atm abs. What is the power required for the compressor if n = 0.6 and the mass flow rate of the gas? Flow conditions are isothermal and the temperature of the gas is 300K. Take f-0.01.
