3. FILTER CALCULATION / SIZING The total pressure drop of a filter at a certain flow rate Q is the sum of the housing p and the element p and is calculated as follows: p total = p housing + p element p housing = (see Point 3.) p element = Q SK* viscosity 3 (*see Point 3.) For ease of calculation, our Filter Sizing Program is available on request free of charge. NEW: Sizing online at www.hydac.com 3. p-q HOUSING CURVES BASED ON ISO 3968 The housing curves apply to mineral oil with a density of.86 kg/dm³ and a kinematic viscosity of 3 mm²/s. In this case, the differential pressure changes proportionally to the density. 3....x with ball changeover in L configuration 6,, 4....x with ball change-over in L configuration 6, 4, 8....x with ball change-over in L configuration 3....x with ball changeover in T configuration 4 3.5 3.5.5.5 3 4 5 6,, 4....x with ball change-over in T configuration 3.5.5.5 5 5 75 5 5 6, 4, 8....x with ball change-over in T configuration 3.5.5.5 5 5 5 3 33, 5, 66....x 66, 99, 3....x with ball change-over in T configuration.8.6.4..8.6.4. 5 3 45 6 75 9 3... 3.x.5.5.5 3 4 5 6 7 8 64... 3.x.5.5 4 6 8 396... 3.x.5.5 4 6 8 33, 5, 66....x 66, 99, 3....x with ball change-over in L configuration.5.5 3 4 5 6 E 7.553.5/.6 3
