To convert gpm to lpm, multiply by 3.8
To convert psi to bar, multiply by .069
Flow Capacity Flanged and Grooved
The flow coefficient (Cv) is the number of gallons per minute
of water flowing through a given size restriction at a pressure
drop of 1psi. To obtain the Cv factor for a given size strainer,
read capacity at in ter sec tion with the 1psi pressure drop.
