The validity of orifice equation
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 a… Webdorifice = Βdpipe Equation 11 The orifice diameter is also estimated using the rearranged orifice equation: 0.5 2 4 ∆ = orifice orifice YC P Q d ρ π Equation 12 The 2 estimates of the orifice diameter generated by Equation 8 and Equation 9 are then compared. If the 2 values are equivalent within the tolerance of 0.01 mm, the orifice ...
