A proposed heat engine draws its input heat from a space at 1000 K and rejects the heat to a space at 400 K. The engine is to produce 300 kW of power from a heat input of 900 kW. Is this process possible?
Given: Proposed: TH = 1000 K; TC = 400 K; Q?H=900 kW; W?=300 kW
Compare the actual proposed efficiency to the Carnot efficiency for the heat engine:
nproposed = W?/Q?H = 0.333
nmax = 1 – TC/TH = 0.60
As nmax > nproposed, the process is possible.
