$12\mathrm{.}43$ Moist air at $20C,1\mathrm{.}05$ bar, $85\%$ relative humidity and a vol$-$

umetric flow rate of $0\mathrm{.}3\frac{m^3}{s}$ enters a well$-$insulated compressor op$-$

erating at steady state. If moist air exits at $100C,2\mathrm{.}0$ bar, determine

a$.$ the relative humidity at the exit.

b$.$ the power input, in kW $.$

c$.$ the rate of entropy production, in $k\frac{W}{K}.$
