Problem 3.034

A closed, rigid tank is filled with water. Initially, the tank holds 0.4 lb of saturated vapor and 4.0 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.

A closed, rigid tank is filled with water. Initially, the tank holds 0.6 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.

A system initially contains 2 lb of liquid water at 110ºF and 0.4 lb of ice at 32 ºF. The system attains an equilibrium state, while pressure remains constant at 1 atm. For water, the specific enthalpy change for a phase change from solid to liquid at 1 atm is 144 Btu/lb. If heat transfer with the surroundings is negligible, determine (a) the final temperature, in ºF (b) the amount of entropy produced in the process, in Btu/ºR.

5. (Mixing Problem) A very large tank is initially filled with 100 gallons of water containing 5 pounds of salt. Beginning at time t = 0, a brine solution with a concentration of 1 pound of salt per gallon flows into the top of the tank at 3 gallons per second, the mixture is stirred, and the mixture flows out of the bottom of the tank at 2 gallons per second. (a) Letting w = pounds of salt in the...

A closed, rigid tank fitted with a paddle wheel contains 2.2 kg of air, initially at 200oC, 1 bar. During an interval of 20 minutes, the paddle wheel transfers energy to the air at a rate of 1 kW. During this time interval, the air also receives energy by heat transfer at a rate of 0.5 kW. These are the only energy transfers. Assume the ideal gas model for the air, and no overall changes in kinetic or potential energy....
