piston of area A is forced with a force F in to

piston of area A is forced with a force F in to a cylinder full of oil of density p and viscosity . If there are N tubular openings of diameter d in the piston, show that the rate of descent of the piston is NTFd4 V = 128AL 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
