A closed, rigid container with a volume of 1 m3 contains H2O initially at a pressure of 800 kPa and temperature of 500 C. Heat transfer occurs to the surroundings. At what temperature, in deg C, will condensation start to occur? As cooling continues, what percentage of the total mass will be condensed when the pressure reaches 175 kPa? At that point, what is the volume, in m3, of the liquid water?
A water tank has a height of 120m, and its area of cross-section is 2000m. Water is released from the tank and the water level drops by 1 meter every minute. Find the rate of change in volume.
