You have a piston-cylinder device carnot cycle heat engine containing 1.12 mol of helium (mw-4 kg/kmol, cp 2.5r) as the working fluid. this heat engine receives 4.65 kj of heat from a high-temperature thermal energy reservoir and rejects 2.42 kj heat to a low-temperature thermal energy reservoir at 27.0 °c. a. calculate the high-temperature reservoir temperature (°c). b. calculate the work this carnot heat engine produces (kj). c. calculate the 1st law or thermal efficiency of this carnot heat engine. d. calculate the work interaction (kj) for the adiabatic, reversible expansion step.
