One kg of water in a piston-cylinder assembly,initially at 1.5 bar and 200 C, cools at constant pressure with nointernal irreversibilities to a final state where the water is asaturated liquid. For the water as the system, determine the work,the heat transfer, and the amounts of exergy transfer accompanyingwork and heat transfer, each in kJ. Let T0 = 20 °C, p0=1 bar andignore the effects of motion and gravity.
THERE ARE SOME DIFFERENT ANSWERS TO THIS QUESTION. I FOUND ANANOTHER ANSWER, I HAVE MANY QUESTION MARKS IN MY MIND. ADDITION OFEXERGY TRANSFER ACCOMPANYING WORK AND HEAT SHOULD BE EQUAL TOE2-E1. SINCE ITS INTERNALLY REVERSIBLE. ON THE OTHER HAND WHEN IUSE 'E2-E1=(U2-U1)+P0×(V2-V1)-T0(S2-S1)' I FIND AN ANOTHER NUMBER.PLEASE HELP.
