WebIn the second part of the experiment, compressible gas flow through an orifice was studied. An orifice is an obstruction meter used to determine the flow rate of a fluid. At the orifice, the diameter decreases to a minimum, so the velocity of the fluid reaches a maximum and the pressure reaches a minimum. Bernoulli’s equation (see Equation 2) 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) raw cattle hornsWebOrifices have been used to measure flowrate for thousands of years, but economic pressures recently have dictated a careful evaluation of the procedure. The National Bureau of Standards currently has two major research programs (funded by API and GRI) underway with the goals of increasing the accuracy and range of orifice measurements.
