Stoke's law states that the viscous drag force F experience by a sphere of radius a, moving with a speed v through a fluid with coefficient of viscosity η, is given by F =6πηav If this fluid is flowing through a cylindrical pipe of radius r, length l and a pressure difference of P across its two ends, then the volume of water V which flows through the pipe in time t can be written as Vt=k(Pl)aηbrc Where k is a dimensionless constant. Correct values of a, b and c are |
