A rigid, poorly insulated tank with a volume of V1.0 m3 initially contains a saturated water vapor (quality of 1.0) at a pressure of 3 bars (300 kPa). The tank is connected to a supply line valve is opened and 2.0 kg of steam enters the rigid tank, after which the valve is closed. The pressure is measured after the valve is closed and it is found that p2-5 bars (500 kPa). Find (a) the state of the...
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.

SP04 A rigid, poorly insulated tank with a volume of V1.0 m3 initially contains a saturated water vapor (quality of 1.0) at a pressure of 3 bars (300 kPa). The tank is connected to a supply line containing steam at a pressure of pL- 10 bars (1000 kPa) and a temperature of TL 500°C. The valve is opened and 2.0 kg of steam enters the rigid tank, after which the valve is closed. The pressure is measured after the valve...
PROBLEM A rigid tank with a volume of 2.4 m3 contains a moist air mixture having 2.7 kg of dry air at a dry bulb temperature of 26°C and a total pressure of 1 atm. Determine the relative humidity of the air, the mass of water vapor in the tank, and the internal energy of the air (in kilojoules).
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...
Problem 5: A rigid tank contains 3.52 kg of an ideal gas. The volume of the tank is V 1.20 m3 and initially the gas is at a pressure of Pi 225 kPa. The tank is charged by adding 0.74 kg of the same gas at which point the new pressure is 450 kPa and the new temperature is 153.94 °C. Determine the gas constant, R, a possible identity of the gas, the original temperature, T, the original density, pi,...
1. A rigid (constant volume) tank sealed by a valve initially contains 100 kg of air at a pressure of 100 kPa and 300 K. At time t = 0, the valve for the air tank is opened in a controlled manner and air leaks out isothermally (constant temperature) of the tank at a constant mass flow rate of 1 kg/s. The valve is closed after 75 seconds. Answer the following questions: Assuming air is an ideal gas, what is...
