WebPipe Flow Liquid Flow Rate is a flowrate calculator app from Pipe Flow Software that calculates the fluid flow rate in a pipe for a given pressure loss (includes friction losses and fitting losses). It uses the Darcy-Weisbach equation with Colebrook-White friction factors, together with K values for fittings, to provide accurate calculations.
