Description : Why flow is measured in square root?
Last Answer : Flow varies directly as the square root of different pressure F = K square root of D/P. 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.
