Abstract
WHEN considering the conditions necessary for the stability of laminar flow in a cylindrical pipe, it may be assumed that the following quantities are involved : transverse velocity gradient (dv/dx) at the point considered; distance (x) of the point from the wall ; and kinematic viscosity (v) of the liquid.
