Question

the efficiency of Carnot engine is 3/4 now the themprature of sink is increaswd by 1100 degree celsius then efficiency is 8/9 yes of intial efficiency then find out temperature of sorce​

Answer 1

Explanation:

(Ts--Tc)/TS= 0.25

{Ts--(273+27)}/Ts=0.25

Ts--300= 0.25Ts

0.75Ts= 300

Ts= 300/0.75= 400

t= 400–273= 127°c
