My conclusion from this paper, holding other parameters constant, flow rate
varies with the square root of nozzle diameter.

Makes sense, but I'd also bucket-test one before
drilling them all.

Bernoulli teaches that flow rate goes with the squair root of pressure
and squair of area assuming the nosel factor dosen't change

CORRECTION squair of area should be squair of diameter
