Flow through an orifice equation
WebSteam flow through a sharp-edged orifice W=0.24725*P*D2 Steam flow through a sharp-edged orifice W=24.24*P*D2 Where W is leakage rate in kg/hr. P is absolute pressure drop across the orifice (gauge pressure added to atmospheric pressure) in bar. D is inner diameter of the orifice in mm. W = leakage rate lb/hr WebThe discharge coefficient is a dimensionless number used to characterise the flow and pressure loss behaviour of nozzles and orifices in fluid systems. Orifices and nozzles are typically used to deliberately reduce …
