Q$3(25\%).$ In a reheat cycle, steam at a rate of $20k\frac{g}{s}$ leaves the boiler and enters the turbine at

${?}^8$MPa,$450C.$ After expansion in the high pressure turbine to $800$ kPa $,$ the steam is reheated to

$40C$ and then expanded in the low$-$pressure turbine to $5$ kPa $.$ The High pressure turbine has an

isentropic efficiency of $80\%$ and the low pressure turbine has an isentropic efficiency of $70\%.$

Determine the net power produced and the cycle efficiency.

ANSWERS: $22\mathrm{.}92$ MW$,31\mathrm{.}3\%$
