1. Two cubic-meters of CO, gas (MW = 44 kg/mol) measured at 100 kPaa, 30 °C are withdrawn from a 1.7
m diameter spherical tank containing CO2 gas initially at 700 kPaa and 60 °C. What is the pressure
(kPaa) of the gas remaining inside the tank
2. A drum 0.5 ft in diameter and 45 inches long contained acetylene at 350 psia, 90 °F. After some of the
acetylene was used, the pressure was 200 psia and 85 °F. a) determine the amount of acetylene that
was used (Ibm). b) What volume would the used acetylene occupy at 14.7 psia, 80 °F (ft°) ? R for this
gas is 59.35 ft-lb/lb.R.
its temperature is 55 °C?
