In Carnot engine efficiency is 40 % at hot reservoir temperature T . For efficiency 50 % , what will be temperature of hot reservoir?

Step-by-step solution

The efficiency of a heat engine is defined as the ratio of work done to the heat supplied, ie, = Work done Heat input = W Q or =1- T₂ T₁ where T₂ is temperature of sink, and T₁ is temperature of hot reservoir 40 100 =1- T₂ T₁ T₂ T₁ =0.6 T₁=0.6 T₁ Again, 50 100 =1- T₂ T₁^ T₂ T₁ ^ =0.5 array ll & 0.6 T₁ T₁ ^ =0.5 & T₁ ^ = 0.6 0.5 T₁= 6 5 T array
