How to calculate the length of the snake tube?
Thread Content
Add a coil radius to the outer surface of the cylinder of φ325×8. The coiled tube is φ32×3.5 seamless steel pipe. The center distance of the side-by-side tubes is 90 and arranged in 10 rows. How to calculate the total length of the coil? Also, what is the formula for calculating the circumference of an ellipse? The major axis of the ellipse is "the outer diameter of the cylinder plus 2 times the diameter of the tube", or "the outer diameter of the cylinder plus 2 times the radius of the tube", or just "the outer diameter of the cylinder". Confused! It needs to be solved urgently! It would be better if there are other related examples to analyze. Thank you so much! Thank you.
If you can’t see the question clearly, it’s best to provide a picture. Approximate formula for the perimeter of an ellipse: L＝π/2(6(a^2+b^2)+4 * a * b)^(1/2) a minor axis, b major axis, π pi
The length of each coil coil: L=^0.5 D is the center diameter of the coil coil； h is the coil spacing.
