Answer / rajesh
generally flow measurent using diffrential is based on
bernoulis theorem.i.e cofficient of dicharge*square root of
diffrentails pressure

Answer / ravi
where orifice plate is used to measure flow alone, the
signal is square rooted. it is by the formula Q=K square
root of Differential pressure. If other types of FT are
used then the signal from that FT need not to be square
rooted.

when magnetic flow meter is used flow is linear
emf= v*B*L
V=VELOCITY OF FLOW
b=magnetic field
l=diameter of pipe

Answer / pankaj
When flow is turbulent, the pressure drop through a restriction is proportional to the square of the flowrate. Therefore, flow can be measured by taking the square root of a differential pressure cell output.

Answer / kalaiselvan
flow directly proportional to square root of differential
pressure so we measure flow in square root
Q = SQARE ROOT OFF DIFFERENTIAL PRESSURE

Answer / faiyaz ahmad
flow is directly proportional the square root to measure a differential pressure that is why flow always measure in square root.

Answer / zia
Flow varies directly proportional to square root of differential pressure F = K square root of AP. 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.

Answer / shahzad
due to the high variation of flow measurements that's why we use square root in flow measurements.
