What is the size of the cut out wedge for 16" x 10" duct that is 36" long and must offset 3"?

To determine the size of the cut out wedge for an offset in a duct, it's important to focus on both the dimensions of the duct and the required offset distance. In this case, we have a rectangular duct that is 16 inches high by 10 inches wide and needs to be offset by 3 inches over a length of 36 inches.

When calculating the cut out wedge for an offset, a common approach involves using the formula for the wedge cut. This calculation typically involves determining the angle created by the offset. The correct wedge cut will allow the duct to accommodate the change in direction while maintaining airflow efficiency.

For a 3-inch offset over a 36-inch length, the cut out wedge should be sized so that the angle between the original duct layout and the newly angled duct maintains structural integrity and aligns correctly. The calculation leads to determining the dimensions needed to create a new cutting shape that reflects this offset.

In this situation, the size of 13/16 inch correlates to the necessary wedge size to create a proper transition for a 3-inch offset in the design of the duct run. This acknowledges the requirements of maintaining functionality while allowing for a smooth airflow transition.

Selecting 13/16 inch therefore is valid based on the required offset
