"Vapor Pressure of Water" assignment: VAPOR PRESSURE OF WATER INTRODUCTION All liquids exist in equilibrium with the vapor state. As temperature increases, this equilibrium shifts more and more in favor of the vapor until one reaches the boiling point, at which all liquid is converted to gas. The pressure exerted by the vapor over the liquid is known as its vapor pressure and is a function of temperature. Boiling occurs at the temperature at which the vapor pressure is equal...
1. Find in your text or a reference table the vapor pressure of water versus temperature. Determine the boiling point of water at 17.5 torr. 2. An inert gas occupies volume of 796 ml at temperature 41 oC and pressure 361 Torr. What volume does the gas occupy at standard ambient temperature and pressure (SATP)?
Water vapor enters a diffuser at a pressure of 0.7 bar, a temperature of 160°C, and a velocity of 180 m/s. The inlet to the diffuser is 100 cm The exit conditions from the diffuser are: velocity of 60 m/s and pressure of 1.0 bar. During the passage of the water vapor through the diffuser, there is heat transfer to the surroundings of 0.6 kJ/kg. Determine (a) the final temperature. (b) the mass flow rate in kg/s, and (c) the...
Water, initially saturated vapor at 11.5 bar, fills a closed, rigid container. The water is heated until its temperature is 200°C. For the water, determine the pressure at the final state, in bar.

Using the vapor-pressure curve in Figure 10.28, estimate the temperature at which water boils when the pressure is 1.5 kPa.
2) A) Water, initially saturated vapor at 10.8 bar, fills a closed, rigid container. The water is heated until its temperature is 200°C. For the water, determine the heat transfer, in kJ/kg. Kinetic and potential energy effects can be ignored. B) A piston-cylinder assembly contains 2 kg of water at 210.6oC and 3 bar. The water is compressed to a saturated vapor state where the pressure is 50.7 bar. During compression, there is a heat transfer of energy from the...
