## Homework Statement

The velocity profile between two plates separated by a distance,

*h*=2 {m}, has a flow distribution given by:

The dynamic viscosity of the fluid is given as 1.5E-1 {Pa s}. The upper wall is moving at velocity

*u*of 7 {m/s}. The pressure gradient dp/dx is -0.015 {Pa/m}. Find the shear stress at

_{0}*y=0.8*{m}.

**Input your answer to in {N/m2} or {Pa} to four decimal places.**## Homework Equations

## The Attempt at a Solution

I feel like this problem should be just plug and chug, but my units aren't working out to be in Pa.

u(0.8m)=(7m/s)(0.8m/2m)+(1/(2*(1.5E

^{-1})Pa*s))(-0.015Pa/m)((0.8m)

^{2}-1.6m

^{2})

I keep getting 2.85 m/s
