This option is used to select what kind of calculation the user wishes to implement.
This option is used to select which set of equations to apply to the cone whether it be those associated with the v-cone or the wafer cone flow meter.
The rest of the options that can be encountered in this calculation can be found in the calculations referenced above.
Mass Flow Rate
The mass flow rate is calculated using the formula shown in C272. Further flow rate outputs, if required, are calculated using one of the flow rate converters using this value of mass flow rate.
The cone diameter is calculated according to the process described in C274.
The differential pressure is solved as described in C273.
