A Carnot engine has an efficiency of 196 It operates between

A Carnot engine has an efficiency of 19.6%. It operates between constant-temperature reservoirs differing in temperature by 62.9 C degree . In kelvins, what are (a) the temperature of the hot reservoir and (b) the temperature of the cold reservoir?

Solution

temperature of the hot reservoir is,

   T_H = dT/e = 62.9 K / 0.196 = 320.9 K

temperature of the cold reservoir is,

   T_L = T_H - dT = 320.9 K - 62.9 K = 258 K
