Water is flowing from point A to point B as shown in the following figure. traveling upward.Consider that the flow is unsteady. The pressure of the liquid at the entrance is and that at the exit is . . Furthermore, the diameter of the pipe is non-uniform; hence there is a velocity gradient in both the x and y directions. The diameter is D 1 at the base and D 2 at the top. The average diameter is D. The Navier Stokes equation for this type of flow is approximated as:a. Find the corresponding non-dimensional equation, where the coefficients will be Reynolds number, Euler number, Froude number and L/D.
