QUESTION 4 If 7.56103kgmol/s of methane gas is to be compressed by a single-stage compressor from 137.9kPa (abs) to 551.6kPa (abs) at 26.7C, calculate: (a) the power required if the mechanical efficiency is 80% and the compression is adiabatic. (10) (b) the power required if the mechanical efficiency is 80% and the compression is isothermal. N.B. The ratio of heat capacities, y for methane is 1.31
