Earth radius k-factor formula
WebAs the curvature of light can be calculated from the Refraction Coefficient: , we get that for a flat earth to appear as a Globe, k FE has to be negative which implies a negative curvature of light, light must bend upwards. Refraction Factor, Apparent Radius of Earth. Many calculations for observations that involve the radius of the earth R, like for hidden … WebMar 7, 2024 · K-factor = [ (180 × BA) / (π × Bend angle complementary × Mt)] – (Ir / Mt) Of course, it’s easiest to use a known K-factor from a table, like in Figure 2. You can use this K-factor and the inside bend radius to calculate the neutral axis. Then use the neutral axis radius to calculate the arc length of the neutral axis—which equals your BA.
