So if you have a ROUND drilled hole then the simplest way to calculate the area is by using pi x radius squared ... and to obtain the radius of the ROUND hole one would use either internal calipers or an internal vernier or the like to measure the DIAMETER and simply divide this by two to gain the radius...
In the event (as mentioned) that a hole was drilled that was not round then Yes! obviously differing calculative formulation is used to determine area prior to flow calculations being used.
So after all this it is necessary to know the diameter in order to calculate the area in order to use 'XXX' formula for flow rates etc?
So perhaps we've all been going around the houses a bit to reach the same conclusion...

Where does one buy those oval drillbits?
