Lesson Thermodynamics Processes
1. An engine bought by an engineer rated a transfer of 5,000 J of energy from a hot reservoir during one cycle and dissipated 3x10³J. Find the efficiency of the engine.
2. A particular heat engine has a mechanical power output of 5.00 kW and an efficiency of 25.0%. The engine expels 8.00x10³ J of exhaust energy in each cycle. Find (a) the energy taken in during each cycle and (b) the time interval for each cycle
