Flowrate Calculation for an Orifice Flowmeter - eFunda

WebThe pressure across the pipe reduces as the fluid flows through an orifice. The fluid properties are also measured using this phenomenon. The orifice flow equation may be expressed as: The orifice flow equation yields the mass flow rate, or discharge Q, through an orifice, given the area of the orifice A. Q = Cd * A * √(2 * g * H) Flow rates through an orifice plate can be calculated without specifically calibrating the individual flowmeter so long as the construction and installation of the device complies with the stipulations of the relevant standard or handbook. The calculation takes account of the fluid and fluid conditions, the pipe size, the orifice size and the measured differential pressure; it also takes account of the coefficient of discharge of the orifice plate, which depends upon the orifice type an… fly things ide
