You are an engineer in an electric-generation station You Known that the flames in the boiler reach a temperature or 1200 K and that cooling water at 300 K is available from a nearby river. What is the maximum thermal efficiency that your plant will ever achieve?

Solution

Yes, 75% is right answer for this in ideal case(carnot cycle)

As per the carnot cycle(Ideal cycle) thermal effieciency=(T1-T2))/T1

Here, T1=1200K, T2=300K

thermal effieciency=(1200-300)/1200

thermal effieciency=0.75
