4. A rigid tank with a volume of 2 m has two chambers, each of 1 m in volume, containing gas 1, with v1-0.8 m3/kg and gas 2 with V2 = 1.2 m3/kg. a. If the two gases are allowed to mix, what is the new specific volume? b. After they mix, a piston compresses the gases until the volume of the tank is 0.5 m What is the final specific volume of the mixed gas after this compression process?...

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,...

Two rigid tanks are connected by a valve. Initially, one tank contains 10 mº of helium (He) gas at 220 kPa, 40°C? The other tank initially contains 4.0 R of neon (Ne) gas at 150 kPa, sot. Now the valve is opened, allowing the two gases to mix with each other. Heat transfer occurs during the mixing process. The final equilibrium temperature is 44'C. The specific heats of monatomic gases are independent of temperature. Determine: (a) the final volume of...

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...

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...

Imagine that you have a 5.50 L gas tank and a 2.00 L gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch. If you fill the larger tank with oxygen to a pressure of 145 atm , to what pressure should you fill the acetylene tank to ensure that you run out of each gas at the same time? Assume ideal behavior for all gases. Butane,...
