Typical sprinkler Discharge Coefficients might be K=5.6 (where the units are in US gpm/psi 0.5) This equates to a metric K of 80.6 (units are in (l/min)/bar 0.5) or K=8.0 (where the units are in US gpm/psi 0.5)Pipe Flow Wizard Fittings and Valves DatabasePipe Flow Wizard comes with its own Fittings Database that contains K factors for many different types and sizes of pipe bends and valves. A fitting's K factor allows the pressure drop across the fitting to be calculated for a specific velocity of fluid flow through the pipe fitting. i.e the pressure drop through the fitting varies depending on k values for pipe fittings metric in japan
