Question:

Starting with Eq. 10–20, show that the energy destruction associated with a simple ideal Rankine cycle can be expressed as i = qin(nth,Carnot - nth), where nth is efficiency of the Rankine cycle and hth,Carnot is the efficiency of the Carnot cycle operating between the same temperature limits.
