Assume ideal gas behavior, and compute the reversible work required to compress a natural

gas mixture from $10$ to $60$ psig $(0\mathrm{.}694\mathrm{.}1$ barg$),$ both isothermally and adiabatically, with an

initial temperature of $80\backslash$deg F $(26\mathrm{.}7\backslash$deg C$).$ Also, calculate the exit temperature for adiabatic

compression. The molar mass of the gas is $18,$ and the ratio of heat capacities is $1\mathrm{.}15.$

Assume the compressor is $100\%$ efficient for this calculation.
