Exercise:
Determine ∆P at 160 gpm (600 L/min) Accessories
for ART85Z5S43Y2 using 175 SUS (44 cSt) fluid. for Tank-
Mounted
Solution:
∆P housing = 1.9 psi [.17 bar] Filters
∆P element = 160 x 0.1 x (175÷150) = 18.67 psi
or PAF1
= [600 x (0.1÷54.9) x (38÷32) = 1.30 bar]
∆P total = 1.9 + 18.67 = 20.57 psi
or MAF1
= [.17 + 1.30 = 1.47 bar]
