.FreeFluids.Pipes.PipeFlow1Ph .FreeFluids.Pipes.PipeFlow1PhAn extension of the PipeFlowBase model for monophasic fluids. The Darcy's friction factor is calculated according to the churchill equation.
The model can be used also for gas flow, provided that the pressure loss is not too high (say less than 40% of inlet pressure) and f*L/D is higher than 2.
