Understanding this result

Inputs: Discharge coefficient, Nozzle diameter (m), Pressure (Pa), Water density (kg/m³). Relationship: cd*π*d*d/4*sqrt(2*p/rho)*1000*60 → L/min

Use the units printed beside each input and compare the result only with values calculated on the same basis.

Interpret the displayed value using the units, assumptions and input values shown in the active tool. Important professional decisions should be independently verified.
