For those who would prefer to calculate it for themselves, the table below gives the intake flange angles. The amounts shown are how much difference there is from 90 degrees between the flange and deck. The flange angles listed below may be used with the following formula: | For those who would prefer to calculate it for themselves, the table below gives the intake flange angles.
