8-Two large porous plates are separated by a distance L. An incompressible constant-property fluid fills the channel formed by the plates; also plates are fixed. An axial pressure gradient dp/dx is applied to the fluid to set it in motion. The same fluid is also injected through the lower plate with a normal velocity V. Fluid is removed along the upper plate at velocity V. The injected fluid is identical to the channel fluid. By Neglecting gravity, If the velocity in x direction (u) depends upon only y. (a)- using continuity and Navier- Stokes equation find velocity in x direction (u). (b)- find the viscous drag at the bottom plate
