An engineer brings you a basic design for a steam power plant. The heat is input to the plant from a source at 500oC, and heat is rejected to cooling water at 20oC. The power plant is to produce 250 MW of power while receiving heat at a rate of 700 MW. Is this process possible?
Given: Proposed: TH = 500oC = 773 K; TC = 20oC = 293 K; Q?H=700 MW; W?=250 MW
