∆P filter = ∆P housing + ∆P element
Exercise: NMF30
Determine ∆P at 85 gpm (320 L/min) for
HS60... using 141 SUS (30 cSt) fluid. RMF60
Solution:
∆P housing = 13.5 psi [0.93 bar] Cartridge
∆P element = 85 x .134 x (141÷141) = 11.39 psi Elements
or
= [320 x (.134÷54.9) x (32÷32) = .79 bar] HS60
∆P total = 13.5 + 11.39 = 24.89 psi
or MHS60
= [.93 + .79 = 1.71 bar]
