Question

Heat in the amount of 150 kJ is transferred directly from a hot reservoir at TH= 550 K to two cooler reservoirs at T₁ = 350 K and T₂ = 250 K. The surroundings temperature is T, = 300 K. If the heat transferred to the reservoir at T₁ is half that transferred to the reservior at T₂, calculate:

(a) The entropy generation in kJ K^-1.

(b) The lost work. How could the process be made reversible?
