Duct Fitting Loss — Calculator

The calculator converts the resistance of a fitting into an equivalent length of straight duct, allowing for easier total pressure calculations.

They calculate the pressure loss in inches of water gauge ("wg) or Pascals (Pa) for various round and rectangular fittings. duct fitting loss calculator

Helps ensure that the total pressure does not exceed the capacity of the air handling unit (AHU). The calculator converts the resistance of a fitting
