SF_27
Function SF_27(r_1, r_2) returns the shape factor for conduction through a truncated hemisphere.
The calling protocol is:
S= SF_27(r_1, r_2)
Inputs:
r_1 radius of the truncated surface [m or ft]
r_2 radius of the hemisphere [m or ft]
Output:
S shaper factor [m or ft]

Example:
$UnitSystem SI Mass J K Pa
$VarInfo S units=m
r_1=0.022 [m]
r_2=0.044 [m]
S=sf_27(r_1, r_2)
{Solution:
S=0.105 [m]}
