pub const ETA_BY_FINENESS: [f64; 12];Expand description
A finite circular cylinder’s crossflow drag over an infinite one’s, η, at ETA_FINENESS,
at very low crossflow Mach number: NASA TR R-474, Fig. 4 (printed p. 77), the curve for a
circular cylinder at a crossflow Reynolds number of 88,000 (from Goldstein), read by hand to
about ±0.005. Held outside 2 to 40.
