A cycle is completed as described: heat, Q1 is added isothermally at temperature T1=4,500°R: after an isentropic process to T2=1,680°R, additional heat Q2 is added isothermally; this is followed by an isentropic process to T3=400°R, where heat is rejected isothermally to the sink until an isentropic compression returns to the working substance to its original state. The heats added are proportional to the temperature at which they are received. Calculate the efficiency of the cycle.
