Notes ∆P filter = ∆P housing + ∆P element
Exercise: NMF30
Determine ∆P at 15 gpm (57 L/min) for
RFS508R10OD5 using 200 SUS (44 cSt) fluid.
RMF60
Solution:
∆P housing = 5.0 psi [.38 bar] Cartridge
∆P element = 15 x .30 x (200÷150) = 6.0 psi Elements
or
= [57 x (.30÷54.9) x (44÷32) = .41 bar]
∆P total = 5.0 + 6.0 = 11.0 psi HS60
or
= [.38 + .41 = .79 bar] MHS60
