90-Degree Mitered Corner Length Formula

$$x = w \cdot \left(1.04 + 1.30 \cdot e^{-1.35 \cdot \frac{h}{w}} \right)$$

Where:

• $$x$$ = mitered corner length (mm)
• $$w$$ = elbow width (mm)
• $$h$$ = elbow height (mm)

This equation calculates the effective conduit length around a 90-degree corner based on elbow width and height, accounting for the bend geometry.

90-Degree Mitered Corner – Calculation Example

Given:

• $$w$$ = 50 mm
• $$h$$ = 25 mm

Calculation:

1. $$x = 50 \cdot \left(1.04 + 1.30 \cdot e^{-1.35 \cdot \frac{25}{50}} \right)$$
2. $$x = 50 \cdot \left(1.04 + 1.30 \cdot e^{-0.675} \right)$$
3. $$x = 50 \cdot \left(1.04 + 1.30 \cdot 0.509 \right)$$
4. $$x = 50 \cdot (1.04 + 0.662) = 50 \cdot 1.702$$
5. $$x = 85.1 \text{ mm}$$
