Determine operating pressure
Select the flow factor from the table opposite
Divide the flow in m3/s by the flow factor.
Multiply the answer by 320 to give the required total blade size in linear millimetres
Divide the total by 1, 2, 3 or 4 as appropriate to give individual blade size.
Standard blade lengths :- 200, 250, 260, 300, 330, 380, 430, 470, 520, 550, 610, 650, 680, 720, or 750mm.
Example - 0.22 m3/s @ 22 Pa. Flow factor (from table opposite) = 0.089
Formula : 0.22/0.089 x 320 = 791 (theoretical blade length in mm)
As this is greater than the largest single blade, divide by 2 and round up to the nearest standard size which will indicate a 100 LF430/2 stabiliser.
