Flow of gas through an orifice
WebTask: Calculate flow rate of water flowing through orifice plate with external diameter of 120 mm and internal diameter of 80 mm. Measured pressures in front and after the orifice is 11000 mm H 2 O and 10000 mm H 2 O. Pressure is measured on 1 inch taps. Solution: Flow rate is: 54.674 m3/h. WebEquation-2. Where, a= area of orifice, C d is a hydraulic coefficient named as coefficient of discharge and g= acceleration due to gravity. The value of C d varies from 0.61 to 0.65. 1.2. Large Orifice. If the head of fluid is less than 5 times the depth of the orifice, then it is categorized as a large orifice.
