3-1 The molecular weight of carbon dioxide, CO2, is 44. In an experiment the value y for
CO2 was found to be 1.3. Assuming that CO2 is a perfect gas, calculate the gas
constant, R, and the specific heats at constant pressure and constant volume, Cp, Cv
(0.189 kJ/kg.K; 0.63kJ/kg.K; 0.819kJ/kg.K)
3-2 Oxygen, O2, at 200 bar is to be stored in a steel vessel at 20°C the capacity of the vessel
is 0.04m³. Assuming that O₂ is a perfect gas, calculate the mass of oxygen that can be
stored in the vessel. The vessel is protected against excessive pressure by a fusible plug
which will melt if the temperature rises too high. At what temperature must the plug
melt to limit the pressure in the vessel to 240bar? The molecular weight of oxygen is 32
(10.5 kg; 78.6°C)
3-3 A quantity of a certain perfect gas is compressed from an initial state of 0.085m³, 1 bar
to a final state of 0.034m³, 3.9 bar. The specific heats at constant volume are 0.724
kJ/kg.K, and the specific heats at…
A trapezoidal combined footing 5.5 m long is to supporttwo 400 mm square columns 5 meters apart. The center ofthe columns are both 0.25m away from property lines. Theleft column carries 675 kN while the right column 825 kN.The allowable soil pressure is 126 kPa. Assume footing is0.5m thick with soil backfill 0.7m thick.
