A three$-$stage compressor receives $500$ lps of air at $101$ kPaa and $27$ oC$,$ and

discharges at $750$ kPaa. Determine a$)$ the power required; b$)$ the pressure at each

intercooler; c$)$ the maximum temperature; and d$)$ the heat transferred in each intercooler. e$)$

What is the discharge temperature of a single$-$stage compressor operating at the same

intake and discharge temperatures?
