The formulas to calculate the taper and taper angle are:
\[ T = \frac{{dl - ds}}{L} \]
\[ TA = \arctan \left(0.5 \times T\right) \]
Where:
A taper refers to a section of a pipe or other object that reduces in overall diameter over a certain length. The reduction in size is the taper, and the rate at which it reduces over the length is considered the taper angle.
Let's assume the following values:
Using the formulas to calculate the taper and taper angle:
\[ T = \frac{5 - 3}{10} = 0.2 \]
\[ TA = \arctan \left(0.5 \times 0.2\right) \approx 5.71 \text{ degrees} \]
The taper is 0.2, and the taper angle is approximately 5.71 degrees.
