Q. No 1: Suppose a closed and rigid vessel is initially filled with mixture of saturated liquid and saturated water vapor at 200 kPa. On transferring heat, the water is found to pass through the critical point. Determine the ratio of the volume of saturated vapor to the volume of saturated liquid with which the vessel is initially filled.
Q. No 2: Steam at a pressure of 1.9 MN/m2 and with a temperature of 220oC is expanded to a pressure of 0.32 MN/m2 according to the law PV1.3 = constant. It is then further expanded to a pressure of 0.12 MN/m2. Determine a. The final condition of the steam b. The total work done
