Question

Calculate the efficiency of an engine with an input temperature of 832K and an exhaust temperature of 350K.

Answer 1

efficiency=58.57%

Step-by-step explanation:

efficiency= output/input × 100%

Output= input temperature-exhaust temperature.

Output= 832-350=482K

input= 823K, output= 482K

e= (482/823)×100=58.56622114%

therefore the efficiency of the engine is approximately 58.57.
