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...
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.
