Q$2$: Consider a reheat cycle utilizing steam. Steam leaves the boiler and enters thi $450C.$ After expansion in the turbine to $300$kPa, the steam is reheated to $400C$ and th low pressure turbine to $4$kPa.

a$.$ Determine the cycle efficiency

b$.$ What is the difference between Carnot and Rankine cycle and how efficiency c improved? explain
