Reynold number `N_R` a dimensionless quantity determines the condition of laminar flow of a viscous liquied through a pipe. `N_R` is a function of density `rho` of liquid, average  speed `upsilon` and coeff. Of viscosity `eta.` Given that `N_R prop D,` diameter of pipe. Show by the method of dimensions that `N_R prop(rhoupsilonD)/(eta)`
