Calculation

Mass Flow Rate

The mass flow rate is calculated using the formula shown in C276. Further flow rate outputs, if required, are calculated using one of the flow rate converters using this value of mass flow rate.

Cone Diameter

The cone diameter is calculated according to the process described in C274.

Differential Pressure

The differential pressure is solved as described in C273.
