Laminar flow and turbulent flow: outlet pressure of pumps
Thread Content
Are the local resistance coefficients of pipe fittings and valves the same for laminar flow and turbulent flow? Only the value for turbulent flow was found
Isn’t the local drag coefficient just one? Laminar and turbulent flow along the flow path
Friction coefficient along the flow path: The friction coefficient for laminar flow, which corresponds to the losses along the flow path, is constant, whereas the friction coefficient for turbulent flow varies and depends on the relative roughness of the pipe walls. Local drag coefficient: There is no distinction between laminar and turbulent flow when it comes to the local drag coefficient; since the flow states we encounter are usually turbulent, it is sufficient to use the value for turbulent flow
