The formula to calculate the J Pipe Length (L) is:
\[ L = \frac{D}{\cos(\theta)} + \frac{H}{\sin(\theta)} \]
Where:
Let's say the water depth (D) is 100 inches, the bottom angle (θ) is 30 degrees, and the horizontal offset (H) is 50 inches. Using the formula:
\[ L = \frac{100}{\cos(30^\circ)} + \frac{50}{\sin(30^\circ)} \]
We get:
\[ L = \frac{100}{0.866} + \frac{50}{0.5} = 115.47 + 100 = 215.47 \text{ inches} \]
So, the J pipe length is approximately 215.47 inches.
