What is the miter angle of an 8" diameter, 5 pc 120 degree, HVAC elbow?

To determine the miter angle of an 8" diameter, 5-piece, 120-degree HVAC elbow, it’s important to understand how miter angles work for elbows in ductwork.

In this scenario, the total angle of the elbow is 120 degrees. A 5-piece elbow means that the duct is divided into 5 sections to create the total angle. The calculation for the miter angle involves dividing the total angle by the number of pieces minus one. This is because the first piece does not contribute to the miter contribution, hence we subtract one.

So, for this elbow:

1. The total angle of the elbow is 120 degrees.

2. The number of joints or miter pieces is 5, but we need to consider 5 - 1, which equals 4.

3. Therefore, to find the miter angle, we divide the total angle by the number of pieces minus one:

( \frac{120°}{4} = 30° )

However, as per the configuration of segments and the type of elbow, practical data often indicates adjusting the calculation to fit standard practices and rounding points in the construction field. In this case, the value of 15 degrees derived in
