In a locker room at 20oC (293 K), a football is filled until the gauge reads 12.5 psi or 86 kPa. This is relative to the atmospheric pressure of 101 kPa, so the absolute air pressure in the ball is 187 kPa. The ball is taken out to the field and reaches thermal equilibrium at 10oC. Assuming the volume of the ball is constant, what is the absolute and relative pressure inside the football

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?
