Answer / ahmed helmy
Q= Cv sqrt(delta P/G)
where:
Cv:Flow Coefficient
delta P:the difference between Inlet and outlet pressure
G: specific gravity
so from this equation, we find a relationship between flow (Q) and delta P

Flow varies directly proportional to the sq.root of differential pressure.thatswhy we are using sq root for flow measurement.

Answer / muslim
DP reading is small compare to actual flow so square root
will make the linear relation between Dp and actual
flow.also some time we have to consider the fluid density

During valve sizing from all calculation you got flow coefficient CV 12,than what it means? like for selecting pressure transmitter if your MAWP is 12 bar than you select a capsule of max. 20 bar which cover your mawp 12 in same way for selecting control valve If CV is 12 than how we use it in selecting valve??????
