WitrynaAn orifice with diameter D2 = 50 mm is inserted in a 4" Sch 40 steel pipe with inside diameter D1 = 102 mm. The diameter ratio can be calculated to d = (50 mm) / (102 mm) = 0.49 From the table above the discharge coefficient can be estimated to approximately 0.6 for a wide range of the Reynolds number. Witryna- the measured orifice D1 (in mm) - the material of the orifice plate - the type of orifice plate (Square, Restriction etc.) Letter height approx. 4 mm; Welding of tab Tab may …
