Using the information given in Table 10.4 , determine the ratio of local pressure and density to sea-level values. Estimate the value of air density at the cruising altitude of most commercial airliners.
1. The pressure in an automobile tire depends on the temperature of the air in the tire. When the
air temperature is at 545.67 Rankine, the pressure gauge reads 245 kPa. If the volume of the
tire is 0.025 m', determine the pressure rise (in lbf/in units) in the tire when the air
temperature in the tire rises to 70 °C. Also determine the amount of air that must be bled off
to restore pressure to its original value at this temperature. Assume the atmospheric pressure
to be 101.325 kPa.
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.
