Description : Why Is Flow Measured In Square Root?

Last Answer :  Flow varies directly as the square root of different pressure F = K square root of ΔP.  Since this flow varies as the square root of differential pressure the pen does not directly indicate flow.  The flow can be determined by taking the square root of the pen. Say the pen reads 50% of chart.
