What is the impact of having a pipe made of rough material on the flow?
Hello @Kremella ,
The flow over a rough wall generally leads to higher levels of friction pressure losses.
Yes, you can calculate the friction losses using the Darcy-Weisbach equation. The pressure losses are proportional to the length of the pipe and the Darcy-Weisbach friction factor:
delta_P / L = f_D * (rho / 2) * (V_avg^2 / D )
delta_P - pressure drop
L - pipe length
f_D - friction factor
rho - fluid density
mu - fluid dynamic viscosity
V_avg - average fluid velocity
D - pipe diameter
This equation is valid for incompressible flows.
