Problem 3.034 A closed, rigid tank is filled with water. Initially, the tank holds 1.0 lb of saturated vapor and 6.0 lb of saturated liquid, each at 212°F. The water is heated until the tank contains only saturated vapor. Kinetic and potential energy effects can be ignored Determine the volume of the tank, in ft3, the temperature at the final state, in °F, and the heat transfer, in Btu
4. Nitrogen (M-28.01 lb/ibmol) fills a closed rigid tank fitted with paddle wheel, initially at 80°F, 20 psia, and a volume of 2 ft3. The gas is stirred by the paddle wheel to a final temperature of 300°F During the process heat transfer from the gas to its surroundings occurs in an amount of 1.6 Btu. Assuming ideal gas behavior, determine the mass of gas and the work done. Kinetic and potential energy effects can be ignored. R 1545.bmol R(20...
2.Water, initially saturated vapor at 14.6 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. 3.A piston-cylinder assembly contains 4 kg of water at 211.4oC and 3 bar. The water is compressed to a saturated vapor state where the pressure is 50.8 bar. During compression, there is a heat transfer of energy from the water to its...
Consider a closed, rigid tank with a volume of 0.8L, filled with cold water initially at 300K. The tank is filled such that there are no voids (air pockets) within. The initial pressure within the tank is 1000 kPa. The water is being heated by an unknown source. Assume internal volume of the tank remains constant. Determine necessary equations in variable form. Using the equations from part (a), determine the temperature, in °C, when the water reaches 4000 kPa and...
A 160 m3 rigid tank is filled with saturated liquid-vapor mixture of water at 50oC. 70% of the mass is vapor and the 30% of the mass is liquid. The mixture is then heated until its pressure is 50kPa. Determine the final temperature(oC).
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...

A rigid tank having a volume of 0.1 m3 initially contains water as a two-phase liquid-vapor mixture at 1 bar and a quality of 1%. The water is heated in two stages: Stage 1: Constant-volume heating until the pressure is 20 bar. (treat as closed system) Stage 2: Continued heating while saturated water vapor is slowly withdrawn from the tank at a constant pressure of 20 bar. (Note: Use transient analysis with all the water leaving having a quality of...

A rigid, insulated tank fitted with a paddle wheel is filled with water, initially a two-phase liquid-vapor mixture at 200 kPa, consisting of 0.04 kg of saturated liquid and 0.04 kg of saturated vapor. The tank contents are stirred by the paddle wheel until all of the water is saturated vapor at a pressure greater than 138 kPa. Kinetic and potential energy effects are negligible. For the water, determine...

A 200-m' rigid tank is filled with saturated liquid-vapor mixture of water at 50°C. If 10% of the mass is liquid and the rest is vapor, find the total mass in the tank. If heat is added in and the mixture becomes saturated vapor, find the pressure.
