The formula provides us with a length of any roll of material providing we have the thickness of the material and the inner and outer diameters of the cylinder.
With the approximate formula we get N = 500 and Lapprox = 235.4623694 m. With the exact formula we get φ0 = 1000π, φ1 = 2000π and Lexact = 235.6194545 m. The...
2023年11月20日 — But on the "Roll length calculator" you found, the "approximate" length is L2=π(D0+(N−1)h)N,. using L2 for this estimated length to distinguish...
