42BHC,BVC COMPONENT STATIC RESISTANCE (in. wg)

Hydronic coil pressure drop —

All of the factory’s hy-

dronic coils have a coefficient of velocity (Cv) resistance
factor assigned to assist in a more accurate determination
of water pressure drop (see Cv Factor by Coil and Unit Size
table below).

Calculating pressure drop:
The Cv factor is equal to the flow rate of water in gpm

through a piping component when the pressure drop
through the component is 1.0 pounds per square inch
(psi), or 2.31 ft wg.

∆

P (ft wg) =

∆

P (psi) x 2.31

Use the Cv factor from the Cv Factor by Coil and Unit

Size table to determine the water coil pressure drop.

Coil pressure drop (ft wg):

∆

P = (GPM

/Cv

) x 2.31

∆

P = [GPM/(0.658 x Cv)]

Refer to the Water Pressure Drop for Cv Factor and

Water Flow Rate table. See example on page 22.
