without consideration of inclines and couplings
Restriction and NOTES: The roughness coefficients of the different pipe materials are not taken into account in the calculation, so the determination of the speed and the pressure loss is only an approximation. ²) Entry only with flat hose. The program then takes into account the increasing inner diameter as the pressure increases.:
The flow rate should be between 1.5 and 2.0 m/s.
