Answer / sagar mistry

Because flow is directly proposnal to squareroot of delta p(dp)...(F=sqrt of dp)

Answer / sindhu

its because the flow rate is proportional to square root of differential pressure.

Answer / vidnyan patil

Flow varies directly as the square root of DP. since this
flow varies directly the pen does not indicate flow
directly. The flow can be determined only by taking the
square root of the pen.
