F2D_17

An infinite surface to the second row of an equilateral triangle array of infinitely long tubes

Function f2d_17 returns the view factor from an infinitely long flat plate to the second row of an equilateral triangle array of tubes.

The calling protocol is:

F = f2d_17(d, p)

Inputs:
d: diameter of tubes (ft or m)
p: distance between tube centers both horizontally and diagonally from 1st to 2nd row (ft or m)

Example:
$UnitSystem SI Mass J K Pa Degree
d=1 [m]
p=2 [m]
F=f2d_17(d, p)

{Solution
F=0.1943}
