The depth of the reservoir dam , The depth of thepipe, =15.5m 41m 4.91x10 m0.024m The radius of the pipe ,r 2 Time, 1.78h The magnitude of the frictional force is given by F P,A =pgh,A -(1000kg/m)(9.8m/s)(4.1 1m)(3.14x (0.024)) =72.84 N (a)The magnitude of the frictional forcebetween the plug and the pipe wall is 72.84N
