To save the cost of punching or drilling in a secondary operation the following formulas can be used to calculate the minimum distance required: For a hole < 1" in diameter the minimum distance "D" = 2T + R (see fig. "B")
Webb11 okt. 2013 · With an integral. Calculating the volume of the shape you describe requires knowledge of integral calculus. Furthermore, you need to specify exactly what kind of shape you have--there are infinitely many curves that would "look like" a teardrop, but they would each have a different volume formula. – apnorton Oct 3, 2013 at 12:50 Webbequation, complete with the centrifugal force, m(‘+x)µ_2.
