11-35.A moist air mixture with a dry bulb temperature of 48°C, a relative humidity of 40 percent, and a total pressure of 160 kPa is contained in a rigid vessel having a volume of 1.65 m3. The air is cooled until the dry bulb temperature reaches 23°C. Determine the amount of heat transferred, the final pressure of the air, and the amount of water vapor condensed during the process.

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 (treat as closed system) Stage 2: Continued heating while saturated water vapor is slowly withdrawn from the tank at a constant pressure of 20 bar.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 9.8 m3 rigid tank contains steam at 220°C.
Pressure in tank = 2320 kPaQuality of saturated mixture = 0.0269A 9.8 m3 rigid tank contains steam at 220°C. One-third of the volume is in the liquid phase and the rest is in the vapor form. Determine the density of the mixture. (Round the final answer to one decimal place.) (You must provide an answer before moving on to the next part.) The saturated water-temperature table (in Sl units) is given below.The density of the mixture is _______ kg/m3

An air conditioner operating at steady state takes in moist air at 28ºC, 1 atm and 70% relative humidity. The moist air first passes over a cooling coil in the dehumidifier unit and some water vapor is condensed. The rate of heat transfer between the moist air and the cooling coil is 38.69 kW. Both saturated moist air and condensate streams exit the dehumidifier unit at the same temperature. The moist air then passes through a heating unit, exiting at...

A rigid tank that contains 2.4 kg of N2 at 25°C and 550 kPa is connected to another rigid tank that contains 4.4 kg of O2 at 25°C and 150 kPa. The valve connecting the two tanks is opened, and the two gases are allowed to mix. If the final mixture temperature is 25°C, determine the volume of each tank and the final mixture pressure. The gas constants of N2 and O2 are 0.2968 and 0.2598 kPa.m3/kg.K, respectively. The universal...
