This problem involves a cylinder falling inside a pipe that isElled with oll, as depleted in the figure. The small space between the cylinder andthe pipe is lubricated with an oll film that has absolute viscosity a. (a) Derivea formula for the steady rate of descent of a cylinder with weight W, diameterd, and length t sliding inside a vertical smooth pipe that has inside diameter D,Ansume that the cylinder is concentric with the pipe as it falls. (b) Use the generalformula you derive to find the rate of descent of a cylinder 100mm in diameterthat alides inside a 100.5mm diameter pipe. The cylinder is 200mm long andwelghs 15N. The lubricant is SAE 20W oll with a viscosity of 2.0 x 10-2Pa s.PipeOil filmCylinder

A Water Tank That Needs Cleaning 11 of 18 I Review I Consta A cylindrical open tank needs cleaning. The tank is filled with water to a height ho = 1.00 meter, so you decide to empty it by letting the water flow steadily from an opening at the side of the tank, located near the bottom. The cross-sectional area of the tank is Aj = 0.785 square meters, while that of the opening is A2 = 0.002 square meters. Part A %3D How much time t/2 does it take to empty half the tank? (Note: A useful antiderivative is 1/2 da = 2x/2) Express your answer numerically in seconds. Take the free-fall acceleration due to gravity to be g = 9.81 meters per second per second. %3D • View Available Hint(s) ? t1/2 = Submit Nex Provide Feedback MacBook Air DII DD 000 esc F9 F10 FL F4 F5 F6 F7 FB F2 F3 F1 * @ %23 %24 3 5 8 9 * 00
