The jack in Problem 12.14 is overloaded by 50,000 N. Recalculate the leakage rate and determine how fast the jack will descend.

Problem 12.14

The jack at an auto repair shop can support 50,000 N. The hydraulic fluid has a viscosity µ of 0.2 (N-s)/m². The diameter of the piston is 0.25 m, the piston–cylinder gap width is 1 mm, and the piston in the cylinder is 0.25 m long when fully extended. Estimate the leakage of fluid past the piston.
