If a natural gas has a specific gravity of 0.60 relative to air at 14.70-psi-abs and 68
degrees Fahrenheit.
a. Calculate the density of gas at constant pressure and temperature
b. Determine its specific weight.
The volume and temperature of air (assumed to be
an ideal gas) in a closed vessel is 2.87m³ and 300
K, respectively. The gauge pressure indicated by a
manometer fitted to the wall of the vessel is 0.5
bar. If the gas constant of air is R = 287 J/kg K and
the atmospheric pressure is 1 bar, the mass of air
(in kg) in the vessel is
The pressure in an automobile tire depends on the temperature of the air in the tire. When the air temperature is 25°C, the pressure
gage reads 210 kPa. If the volume of the tire is 0.025 m3, determine the pressure rise in the tire when the air temperature in the tire
rises to 60°C. Also, determine the amount of air that must be bled off to restore pressure to its original value at this temperature.
