Relationship between pressure and flow rate(theoretical formula)

Caution Regarding the Formula: In theory, the Water Flow Rate of a nozzle is proportional to the square root of the pressure of the water at the inlet. In practice, however, the flow rate coefficient may vary according to a nozzle's design, the viscosity of the liquid being sprayed, pressure etc. Consequently, it will be necessary to factor in a correction coefficient. As this formula does not include a correction coefficient, the result of the calculation should be regarded as being for informational purposes only. Find the resulting pressure when the flow rate is changed. Find the resulting flow rate when the pressure is changed.

Orifice Diameter/Liquid Flow Rate
	Find a liquid flow rate from an orifice diameter; conversely, find an orifice diameter from a liquid flow rate. How to use (1) Check the button next to the value you want to ascertain; select your preferred units. (2) Enter values in all remaining fields; select your preferred units for each of them. (3) Click the [Go] button. Flow rate: Q l/min gal/h ml/sec g/sec kg/h l/h ml/min gal/min m³/h cfm m³/min Correction coefficient: C 0<C≤1.0 Orifice diameter: D mm cm inch m (Fraction can be entered.) Pressure: P MPa bar kgf/cm² mAq psi inchAq cmAq mmAq mmHg(Torr) Liquid density: γ g/cm³ kg/cm³ kg/m³     Caution: (1) The following equation is used to calculate the values above: Q=CπD²/4√(2gP/γ)   Q: Liquid flow rate,  C: Correction coefficient,  D: Orifice diameter,   g: Gravity acceleration,  P: Pressure,   γ: Liquid density   (2) Correction coefficient should be 0<C≤1.0 (used to compensate for calculation errors owing to a deceleration of fluid velocity caused by the inner structure of a nozzle, or to a decrease in flow rate caused by stream shrinkage when liquid is streaming from an orifice). The coefficient differs according to pressure and to the type of nozzle. For example, for flat spray nozzles, the coefficient is stable regardless of pressure. For full cone nozzles with internal components, the coefficient will vary considerably according to pressure.
