Point where Shear Stress is 10 Pascals based on sin Velocity Profile

I have changed the velocity from 50 m/s to 15 m/ s and put in the calculations with , so I have now got x = 26.16 m.

I have tried to calculate this based on what you have said.

Firstly I am...

Point where Shear Stress is 10 Pascals based on sin Velocity Profile

I had included acceleration due to gravity because for that part I thought you had to convert the viscosity = μ = 0.0018 Ns/ m^2 to kg/ ms

That formula τw = pi * μ * U / (2 * Boundary layer...
