Document Summary

Home assignment 6 (chapter 6: a heat engine with a thermal efficiency of 40 percent rejects 1000 kj/kg of heat. 2 heat losses from the working fluid at the pipes and other components are negligible: according to the definition of the thermal efficiency as applied to the heat engine, which when rearranged gives. He sink wnet: a steam power plant with a power output of 150 mw consumes coal at a rate of 60 tons/h. If the heating value of the coal is 30,000 kj/kg, determine the overall efficiency of this plant. Answer: assumptions: the plant operates steadily, properties: the heating value of coal is given to be 30,000 kj/kg, the rate of heat supply to this power plant is. Then the thermal efficiency of the plant becomes. Hlhhqqqqwththnet kj/kg 1667 4. 01kj/kg 10001th lhqq mw 500kj/h 101. 8kj/kg 30,000kg/h 60,0009coalhv,coal qmqh 30. 0% 0. 300mw 500mw 150outnet,thhqw 3.
