1 kg of water steam contained in a piston-cylinder assembly at 3 bar and 160 oC is expanded adiabatically to 0.7 bar. The expansion only produces 90% of the work produced isentropically under the same initial conditions and the same final pressure. (a) Determine the actual work produced during the expansion process, in kJ. (b) Find the entropy production of the expansion process, in kJ/K. (c) Sketch the actual and isentropic processes on a carefully labeled T-s diagram.
