Answer:
Hello your question is incomplete attached below is the complete question
answer :
U/r = R = [tex]U_{max}[/tex] [ 1 - [tex](\frac{R}{R} )^2[/tex] ] = 0
∴ No slip condition is satisfied
Explanation:
Given that
Outlet velocity U(r) = [tex]U_{max}[/tex] [ 1 - [tex](\frac{r}{R} )^2[/tex] ]
prove that the output velocity profile satisfies the no slip condition
at no slip u = 0 ( i.e. at the pipe's inner surface )
at , r = R ( inference is at center )
hence U/r = R = [tex]U_{max}[/tex] [ 1 - [tex](\frac{R}{R} )^2[/tex] ] = 0
∴ No slip condition is satisfied
