To calculate the Duct Bend Area:
\[ A = (W + H) \cdot 2 \cdot \left( (R + \frac{W}{2}) \cdot 3.14159 \cdot \frac{a}{180} \right) \cdot Q \]
Where:
A duct elbow is a bend in an air duct that changes the direction of the duct and airflow. Calculating the area of the bend is important for understanding how air will flow through the bend.
Let's assume the following values:
Using the formula:
\[ A = (0.5 + 0.3) \cdot 2 \cdot \left( (1 + \frac{0.5}{2}) \cdot 3.14159 \cdot \frac{90}{180} \right) \cdot 1 = 0.8 \cdot 2 \cdot (1.25 \cdot 3.14159 \cdot 0.5) \cdot 1 = 0.8 \cdot 2 \cdot 1.963495 \cdot 1 = 3.142 \text{ square meters} \]
The Duct Bend Area is approximately 3.142 square meters.
Let's assume the following values:
Using the formula:
\[ A = (0.6 + 0.4) \cdot 2 \cdot \left( (1.2 + \frac{0.6}{2}) \cdot 3.14159 \cdot \frac{45}{180} \right) \cdot 1 = 1.0 \cdot 2 \cdot (1.5 \cdot 3.14159 \cdot 0.25) \cdot 1 = 1.0 \cdot 2 \cdot 1.1780975 \cdot 1 = 2.356 \text{ square meters} \]
The Duct Bend Area is approximately 2.356 square meters.
