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 44°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 100 kpa.

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

Asolid cylinder is concentric with a straight pipe. the cylinder is 0.5 m long and has an outside diameter of 8 cm. the pipe has an inside diameter of 8.5 cm. the annulus between the cylinder ad the pipe contains stationary oil. the oil has a specific gravity of 0.92 and a kinematic viscosity of 5.57 x 10-4 m2/s. most nearly, what is the force needed to move the cylinder along the pipe at a constant velocity of 1 m/s?
