Homework Statement
http://scienceofdoom.files.wordpress.com/2010/12/convection-basics-1b.png
How do I find the total force on that surface of the plate?
Homework Equations
T = μ * u'(y)
where T is the shear stress, μ is a scalar constant - the viscosity and u'(y) is the velocity gradient in the perpendicular direction
Force = T * A
The Attempt at a Solution
[/B]
Does every point along the plate have a different u(y) distribution so that the shear stress at the surface, μ * u'(y=0) , is different for all of these points?
And so the total force is the sum of μ * u'(y=0) * A for all of those points?
