7.17 A piston of area A is forced with a force F in to a cylinder full of oil of density p and viscosity µ. If there are N tubular openings of diameter d in the piston, show that the rate of descent of the piston is NTFd4 V = I 28HA²L where L = length of piston. Assume that there is no oil leak between the piston and the cylinder and further laminar flow through the tubular openings can be assumed. %3D

7.17 A piston of area A is forced with a force F in to a cylinder full of oil of density p and viscosity µ. If there are N tubular openings of diameter d in the piston, show that the rate of descent of the piston is NrFd4 V = 128µA²L where L = length of piston. Assume that there is no oil leak between the piston and the cylinder and further laminar flow through the tubular openings can be assumed. %3D
