Question

A Carnot engine operating between temperatures Th = 525 K and Tc = 270 K has a power output of Pena- 1350 kilowatts At what rate does the engine remove energy at the higher temperature? kW At what rate does the engine discharge energy as heat at the lower temperature? kW What relationship can Kim say applies among len, IQhl 1Qdl and P? Qhl d and P." "There is no relationship among The product of IOhl and lQcl equals P." At At "The sum of hl ande lQcl equals P." At At "The difference of T and Tedl equals P." At At

Explanation / Answer

efficiency = 1 - (Th /Tc)

= 1 - (270 / 525)

= 0.486

n Qin = Peng

Qin = 1350 / 0.486 = 2777.8 kW .......Ans

Qout = Qin - Pen = 1427.8 kW ......Ans

the difference of Qh/t and Qc/t is Peng
