Orifice Meter Construction, Working Principle, Discharge Equation
To calculate flow rate, you have to enter the orifice plate throat diameter as well as pipe interior diameter, together with fluid properties - density and viscosity. For a gas as flowing fluid, instead of the density, you can enter gas constant, pressure and temperature at actual conditions. Density is then calculated using a perfect gas state.

The formula governing the Flow Through Orifice Calculator is as follows: Q = Cd * A * sqrt (2 * g * h) Where: Q is the flow rate (in cubic meters per second, m³/s). Cd is the discharge coefficient, dependent on the orifice's shape and size. A represents the area of the orifice (in square meters, m²). g is the acceleration due to gravity.
