Problem $08\mathrm{.}040-$ Exit temperature, work input and entropy of air compressor.

Air enters a compressor steadily at the ambient conditions of $100$ kPa and $22C$ and leaves at $800$ kPa $.$ Heat is lost from the compressor in the amount of $160\mathrm{.}0k\frac{J}{k}g,$ and the air experiences an entropy decrease of $0\mathrm{.}40k\frac{J}{k}g*K.$ Use data from the tables.
