Question

A Carnot engine has an efficiency of 50 % when its source is at a temperature 327 ° C . The temperature of the sink is:, 200 ° C, 27 ° C, 15 ° C, 100 ° C

MARKS App · Accepted Answer

Efficiency of Carnot engine is given by, η = 1 - T sin k T s o u r c e ⇒ 50 100 = 1 - T sin k 327 + 273 K ⇒ T sin k = 1 2 × 600 = 300 K = 300 - 273 ° C = 27 ° C
