The velocity in a pipe in turbulent flow is expressed by the following equation:

where τ is the shear stress in N/m2 at the pipe wall

ρ is the density of the fluid in kg/m3

u is the velocity in m/s

k is a coefficient

You are asked to modify the equation so that the shear stress can be introduced in the units of τ which are lbf/ft2, and the density ρ' for which the units are lb/ft3 so that the velocity u comes out in the units of ft/s. Show all calculations, and give the final equation in terms of u, t, and ρ' so a reader will know that American Engineering units are involved in the equation.
