Reynold’s number (r), a dimensionless quantity determines the condition for laminar flow of a viscous liquid through a pipe. r is a function of density p of the liquid, its speed of flow v and coefficient of viscosity n . r is directly proportional to diameter d of the tube through which it flows. show that r is proportional to pvd/n
