With the JHCTES program and similar programs The "Average Pri Rad" and
"Width of Turns" can be confusing. These two parameters can be easily
coordinated with the OD and ID of the primary spiral. The OD is the outside
diameter of the spiral and ID is the inside diameter of the spiral.

       Pri Width of turns =  (OD - ID)/2
       Pri Average radius =  (ID + Width of turns)/2

Another important parameter to check is the clearance between the pri and
sec coils. This is an output with the JHCTES program.

        Pri to Sec clearance = (IR - RS)
The IR is the inside radius of the primary spiral and the RS is the radius
of the secondary coil. The clearance changes when the "Pri Average radius"
is changed so the clearance must be checked when changes are made to the Pri
Average radius.
