SR_6
The function SR_6(a, N, k) returns the thermal resistance between the surface of a regular polygon contact area that is exposed to a uniform heat flux and is located on the surface of a semi-infinite half-space. The resistance is based on the center temperature of the polygon.
The calling protocol is:
R = SR_6(a, N, k)
Inputs:
a = radius of the circle inscribed within the polygon [m or ft]
N = number of sides
k = thermal conductivity of the material [W/m-K or Btu/hr-ft-R]
Outputs:
R = resistance [K/W or R-hr/Btu]

Example:
$UnitSystem SI Mass J K Pa Radian
$VarInfo R6 units=K/W
a=1 [m]
k=1 [W/m-K]
N=3 [-]
R6=sr_6(a,N,k)
{Solution:
R6=0.242 [K/W]}
