If working in units of bars & L/min, divide above factor KC65
by 54.9.
Viscosity factor: Divide viscosity by 150 SUS (32 cSt).

Notes ∆P filter = ∆P housing + ∆P element
Exercise: NMF30
Determine ∆P at 15 gpm (57 L/min) for
YF308YZ10SD5 using 200 SUS (44 cSt) fluid.
RMF60
Solution:
∆P housing = 7.0 psi [.48 bar] Cartridge
∆P element = 15 x .38 x (200÷150) = 7.6 psi Elements
or
= [57 x (.38÷54.9) x (44÷32) = .54 bar]
∆P total = 7.0 + 7.6 = 14.6 psi HS60
or
= [.48 + .54 = 1.02 bar] MHS60
