3-73
The pressure gage on a 2.5m3 oxygen tank reads 500 kPa. Determine the amount of oxygen in the tank if the temperature is 28 deg C and the atmospheric pressure is 97 kPa.
3-74
A rigid tank contains 9 kg of air at 140 kPa and 20 deg C. More air is added to the tank until the pressure and temperature rise to 250 kPa and 30 deg C, respectively. Determine the amount of air added to the tank.
