Write a small computer programme using Excel's Macro that is able to solve numerically via the iterative method the Couette flow with pressure gradient with the governing equation, boundary conditions and geometry shown in Figure A1 below. The programme should be able to accept the followings as input: U = the velocity of upper plates, m/s h = the height of the fluid-filled space, m mu = the fluid's dynamic viscosity, N.s/m2 C = the pressure gradient, N/m3 n = the number of nodes (4<>
