Answer to (a) should be 3.75 kJ/K

3. Inside a closed, rigid container, 6kg of water is initially at 22MPa and 350C (State 1). The water is cooled by heat transfer to the surroundings until the temperature of the water is 275C ( State 2). The surroundings are at 40C. (a) Find the total entropy generated during this process (in kJ/K ). (b) Draw the process on a Pv diagram. Points 1 and 2 should be in the right place with respect to saturation lines and the process line joining them should be the right shape. dings at 40C
