F3D_51

Two opposite walls of a hexagonal prism

Function f3d_51(l,h) returns the view factor between opposite walls of a hexagonal prism.

Inputs:
l = edge of prism [m] or [ft]
h = height of wall [m] or [ft]

Example:
$UnitSystem SI Pa J K m radian
l=0.1 [m]
h=0.5 [m]
F=f3d_51(l,h)
{Solution: F=0.2089}
