A pipe fitted with a closed valve connects two tanks. One tank contains a 5-kg mixture of 62.5 percent CO2 and 37.5 percent O2 on a mole basis at 30°C and 125 kPa. The second tank contains 10 kg of N2 at 15°C and 200 kPa. The valve in the pipe is opened and the gases are allowed to mix. During the mixing process 100 kJ of heat energy is supplied to the combined tanks. The temperature of the mixture after mixing process is 39.4C. Draw
A pipe fitted with a closed valve connects two tanks. One tank contains a 5-kg mixture of 62.5 percent CO2 and 37.5 percent O2 on a mole basis at 30°C and 125 kPa. The second tank contains 10 kg of N2 at 15°C and 200 kPa. The valve in the pipe is opened and the gases are allowed to mix. During the mixing process 100 kJ of heat energy is supplied to the combined tanks. The temperature of the mixture after mixing process is 39.4C. Draw the schematic diagram of the system and all the data displayed on it. List all the appropriate assumption before analysing the problem. Use subscript ‘m’ to designate mixture. After mixing process, determine (a) the total volume of the mixture and (b) the final pressure
of the mixture. Consult the appropriate property tables for the molar masses and gas constants of the constituent gases from the separate PDF file provided on the portal.
