Four kilograms of water initially at 200 degree Celsius and 0.5 MPa undergo an isothermal, internally reversible compression process to the saturated liquid state. Determine the work and heat transfer involved in the process (in kJ). Sketch the process on P-v and T-s coordinates. Associate the work and heat transfer with the areas on these diagrams.
Determine the temperature and phase of water from the following information. If the phas is a vapor-liquid mixture, report the fraction of vapor and liquid.
