An inventor claims a new cyclic engine that uses organic grape juice as its working material. According to the claims, the engine absorbs 1250 J of heat from a 1010-K reservoir and performs 1120 J of work each cycle. The waste heat is exhausted to the atmosphere at a temperature of 302 K. (a) What is the efficiency that is implied by these claims? (b) What is the efficiency of a reversible engine operating between the same high and low temperatures used by this engine? (Should you invest in this invention?)
