Exercise: PLD16DVZ3F24VM
Determine ∆P at 75 gpm (284 L/min) for 16DVZ3 using NMF30
200 SUS (44 cSt) fluid.

Solution:
∆P housing = 20 psi [1.38 bar]
∆P element = 75 x .18 x (200÷150) = 18 psi Cartridge
or Elements
= [284 x (.18÷54.9) x (44÷32) = 1.24 bar]
∆P total = 20 + 18 = 38 psi HS60
or
= [1.38 + 1.24 = 2.62 bar]
