Answer / gk3000

You can use Q = sq.root of DP

where Q = Flow rate
DP = differential pressure.

Answer / jazz

Flow = K x sq. root of dP, where K is the constant of the flow element, dP is the differential pressure produced.This formula assumes that liquid density of media is constant.

Answer / kk

flow Q = K * Sqrt of(dp/fluid density)

Answer / sankar

Flow = k. sqrt of dp.

K= Max flow through flow element / Maximum Dp created by
flow element

Explain, and give a real-world example of MODULATING control
