Air is compressed by a compressor from $101$ kPa and $27\backslash$deg C to $400$ kPa and $220\backslash$deg C at a rate of $0\mathrm{.}15$ kg$/$s$.$ Neglect the changes in kinetic and potential energies and assume the surroundings to be at $25\backslash$deg C$.$ Using appropriate software, investigate the effect of compressor exit pressure on reversible power. Vary the compressor exit pressure from $200$ to $600$ kPa while keeping the exit temperature at $220\backslash$deg C$.$ Plot the reversible power input for this process as a function of the compressor exit pressure.
