From this paper
An iron cube at a temperature of 400◦C is dropped into an insulated bath containing 10 kg water at 25◦C. The water finally reaches a temperature of 50◦C at steady state. Given that the specific heat of water is equal to 4186 J/kg.K. Find the entropy changes for the iron cube and the water. Is the process reversible? If so, why?
A diesel engine has a compression ratio of 15 and heat addition at constant pressure takes place at 6% of stroke. Find the air standard efficiency of the engine. Take γ = 1.4.
