Water vapor initially at 10 bara and 400°C is contained within a piston-cylinder assembly. The water is cooled at constant volume until its temperature is 150°C. The water is then condensed isothermally to saturated liquid. Sketch the process in T-v coordinates. Clearly label the three states. For the water as the system, (a) write the symbolic equation for the specific work (and simplify), w; and (b) evaluate the specific work, in kJ/kg.
