Calculation of Flight Blank for Augers

[BillV 14]

I have to insert a formula (in a worksheet or vector script) to calculate the metal blank size for a segment of an auger. The finished product will have an outside diameter of 100mm, the central shaft will be 40mm and the pitch will be 150mm. Material is 7mm plate.

What is the formula to calculate the metal blank size which is used to create this?

Bill,

The attached sheet is an old worksheet that we used last century when I was designing screw feeders. Hope it is of use.
