At 645.3 kPa and 151.2°C, steam leaves an industrial boiler. When the calorimeter pressure reaches 104.3 kPa, a part of the steam is fed through a throttling calorimeter and expelled to the atmosphere. If the steam temperature at the calorimeter is 113.8°C, a. how much moisture is exiting the boiler container? b. If the mass of the saturated liquid is 15 kg, calculate the mass of the saturated vapor. @ 645.3 kPa and 151.2°C: hf = 624.56 kJ/kg hfg = 2123.3 kJ/kg @ 104.3 kPa and 113.8°C: h2 = 2506.7 kJ/kg
5. The two tanks (Tank A and Tank B) are connected by a valved tube. Initially, the valve is closed. Tank A contains 1 MPa, 1.5 kg of water vapor at 350°C, and tank B contains 3 kg of saturated water with 150 * C and dryness x=0.5. The valve was opened and the water vapor moved and finally the pressure in the two tanks was equal to 300 kPa. Answer the following questions. (1) Calculate the volumes of tank A and tank B, respectively. (2) Calculate the final temperature and dryness (in case of saturation).
A 2 m3 tank initially contains a mixture of saturated-vapor steam and saturated-liquid water at 3200 kPa. Of the total mass, 10% is vapor. Saturated-liquid water is bled from the tank through a valve until the total mass in the tank is 40% of the initial total mass. If during the process the temperature of the contents of the tank is kept constant, how much heat is transferred?

A rigid tank contains 6 kg of an ideal gas at 3 atm and 40°C. Now a valve is opened, and half of mass of the gas is allowed to escape. If the final pressure in the tank is 2.2 atm, the final temperature in the tank is
A 10-kg air is compressed isothermally from 1 atm and 30ºC. If 150 Btu of heat lost by the system, determine the final pressure.
Cold water enters a steam generator at 20°C and leaves as saturated vapor at 200°C. Determine the fraction of heat used in the steam generator to preheat the liquid water from 20°C to the saturation temperature of 200°C.
Steam enters a diffuser steadily at 300 kPa and 300 oC having a velocity of 80 m/s. The inlet diameter of the diffuser is 0.1 m and the velocity at the diffuser exit is very small compared with the inlet velocity. The heat loss from the diffuser to the surroundings is at a rate of 88 kW. If the exit pressure is 800 kPa, determine the phase description and temperature at the diffuser exit. Neglect the potential energy change throughout the diffuser.
A tank with an internal volume of 1 m3 contains air at 800 kPa and 25°C. A valve on the tank is opened, allowing air to escape, and the pressure inside quickly drops to 150 kPa, at which point the valve is closed. Assume there is negligible heat transfer from the tank to the air left in the tank. Using the approximation he ≈ constant = he,avg = 0.5 (h1 + h2), calculate the mass withdrawn during the process.
