Answer Posted / sheik muhammed
flow coefficient of control valve.its calculated by the
given below formula:
CV = Q/(P/SG)^1/2
where:
CV -flow coefficient
Q -flow of liquid
P-pressure drop across the flow
SG-specific gravity of the liquid
CV=1.17KV => KV=.86CV
KV is metric unit of CV
the flow of water through a valve at 60 oF in US
gallon/minute at a pressure drop of 1 lb/in2.

dear friends, i have seen flow as the selection critriea in presure guage (bourdon tube) and i would like to know what is the relation between flow and performance of pressure guage other parameters i found in the data sheet are pressure max. 1ksc temperature max. - 50 deg c line size - 80NB operating range - 1ksc pr. guage range - 0-2 ksc thank u,
