Pump work formula in rankine cycle
Web5-b. A heat pump working on the Carnot cycle takes in heat from a reservoir at 5°C and delivers heat to a reservoir at 60°C. The heat pump is driven by a reversible heat engine which takes in heat from a reservoir at 840°C and rejects heat to a reservoir at 60°C. The reversible heat engine also drives a machine that absorbs 30 kW. WebThermo 2. Practice problem on rankine cycle 1. A steam power plant operates on the cycle shown below.
