10 Kg of water in a piston cylinder exists as a saturated mixture at 120 kpa with quality 40%. the water is now heated so that its volume doubles. the mass of piston is such that a cylinder pressure of 250 kpa will float it off the rests.
1) sketch a P-V diagram of the process, label the states and draw saturated liquid/vapor curve.
2) the final specific volume
3) calculate work done
4) calculate total heat
