A small compressor has a 500 W electric motor. How much energy does the motor consume in 1h in units of Btu and ft-lbf?

A gas flowing at 75 MMscfd (2.1 × 106 Nm3/d) enters a cold section of the plant at 750 psig (51.7 barg) and −40°F (−40°C). Assuming ideal gas behavior, what is the actual flow rate?
