A stream of methane initially at 60 °F and 400 psia is compressed in a single stage compressor to 1000 psia by a compressor with an operating efficiency of 0.85.
a. Determine the temperature of the gas leaving the compressor if the process were adiabatic and reversible.
b. Determine the ratio of densities of the gas entering and leaving the compressor if the process were adiabatic and reversible.
c. Determine the work actually required per pound of methane to compress the gas.
d. Determine the entropy change of the methane during the compression process.
