The pressure in an automobile tire depends on the temperature of the air in the tire. When the air temperature is 25 degC, the pressure gage reads 210 kPa. If the volume of the tire is 0.025 m^3, the pressure rises in the tire when the air temperature in the tire rises to 50 degC. Determine the amount of air, in kg, that must be bled off to restore pressure to its original value at this temperature. Assume the atmospheric pressure to be 100 kPa

onal Assignh Q56. The water in a tank is pressurized by air, and the pressure is measured by a multifluid manometer as shown in the Figure. The atmospheric pressure is 85.6 kPa. Determine the air pressure in the tank if h, = 0.1 m, h2 = 0.2 m, and ha = 0.35 m. Take the densities of water, oil, and mercury to be 1000 kg/m², 850 kg/m², and 13,600 kg/m², respectively. Oil а. 130 КРа Air b. 44 MPa с. 310 КPа Water d. 44 kPa е. 130 MPа Mercury

ii. At temperature T = 250C and pressure 2.25 bar, the volume of gas = 2.5 m3. Subsequently temperature increases to 750C while the pressure remains constant. The volume of gas under the change condition.
