In this problem a heat engine, each cycle, absorbs an amount of energy Qh = 1840 J from a hot reservoir and expels an amount Qc = 1265 J into a cold reservoir. Each cycle lasts for a time of t = 0.21 seconds. Find the efficiency of an ideal engine operating between these reservoirs. Remember the efficiency is unit-less, therefore so should your number be as well.How much power, in Watts, does the engine output per cycle at this efficiency? eideal
