How to calculate the flow rate of compressed air through the orifice
Thread Content
Is it calculated according to the outflow formula of non-compressible gas or the outflow formula of compressible gas? The inflow pressure of the orifice is 0.3~0.4MPa, and the outflow pressure is 0.1MPa
Flow calculation through orifice plate: The basic flow equation illustrates the quantitative relationship between flow and pressure difference. It is derived based on Bernoulli's equation and fluid continuity equation in fluid mechanics, namely: (Due to the editor, the square root is not available and is temporarily replaced with 1/2! ) Q=αεF0 (ΔP) 1/2 (2/ρ) 1/2 (α flow coefficient, ε expansion correction coefficient, opening area of F0 throttling device, actual measured pressure difference before and after ΔP throttling device, fluid density of ρ throttling device)
