A heat engin operates in a Carnot cycle between Tl=80.0 and Th=350.It absorbs Qh=21000J of energy per cycle from the hot reservoir.The duration of each cycle is t=1.0s. What is the mechanical power output of this engine? (95台聯大)Ans:W=Qh(1-Tl/Th)......from textbook=21000(1-(80+273)/(350+273))=21(kJ)(623-353)/623=9.101(kJ)Power=W/t=9.101/1=9.101(kw)
