An idcal gas refrigeration cycle using helium as the working fluid operates between the pressure limits of 200kpa and 600kpa. helium is cooled to 75°c before entering the turbine. calculate the minimum temperature in this cycle. note that helium is an ideal gas with constant specific heats, with k =5/3

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?
