Injector discharge coefficient
Webb5 sep. 2024 · If you want to calculate the discharge coefficient using hydraulic head: Enter the diameter of the orifice if it is circular. Otherwise, enter the cross-sectional area … WebbDischarge Coefficient¶ One important metric in analyzing an injector is the disharge coefficient. It is common to design an injector to obtain a specific “delta-p” (pressure drop across the injector). This is important to ensure combustion stability.
