2. Calculate the efficiency of a Carnot engine operating between temperatures of 400 C and 100 C and n= 44.6%

The efficiency of a Carnot engine depends only upon the temperatures of the two heat reservoirs

efficiency n = (T2 - T1)/T2

T2 = 400 + 273 = 673

T1 = 100+273 = 373

n = 300/673 = 0.4457

n% = 44.57 = 44.6 %
