Qiu’s method for calculating nozzle flow rate
Thread Content
Qiu: Regarding the calculation method for nozzle flow rate – what determines the nozzle flow rate? I only know that in actual applications, changes in factors such as material pressure, temperature, and viscosity cause the actual flow rate of the nozzle to change. Is there any relevant formula or method for this?
Ignoring the viscosity of the liquid: then Q1/Q2 = P1^n/P2^n, where n = 1; for hollow nozzles or non-circular shapes such as fan-shaped ones, n = 0.5； 2. The solid nozzle is 0.46 ； 3. The solid wide-angle one is 0.44 ； Relationship between the specific gravity of the liquid being sprayed: Flow rate = Nominal water spray flow rate / (Specific gravity) × 0.5
