Problem #$8(15$ pt$).$ A water flows between two fixed plates due to a pressure gradient. The gap

distance between the plates is $10mm.$ The pressure difference between the points A and B is $10,000$

$Pa.$ The distance from A to $B$ is $2m.$ Estimate the volume flow rate of water per unit width of the plate.

The viscosity of water $()$ is $1\mathrm{.}0{10}^{-3}k\frac{g}{m}s.$ The water density is $=1,000k\frac{g}{m^3}.$
