(10%) Problem 5: In this problem a heat engine, each cycle, absorbs an amount of energy Q = 1900 J from a hot reservoir and expels an amount Q = 1265 J into a cold reservoir. Each cycle lasts for a time of t = 0.33 seconds. A 20% Part (a) 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. A 20% Part (b) How much work, in Joules, is done per cycle at this efficiency? A 20% Part (c) How much power, in Watts, does the engine output per cycle at this efficiency? A 20% Part (d) What if the actual work done (more realistically) is W = 240 J during a single cycle; what is the efficiency of this engine if the energy input is the same (again, the number should be unit-less)? 20% Part (e) What is equation for the new power output per cycle (in Watts) of this new (and more realistic) engine?
