Computing Speed by Weight

Honestly, I think this link here: http://www.peninsulasilentflyers.co...rs.com/files/documents/Tom_Hunt_prop_info.pdf, is way easier to grasp than the previous link listed. I'm not sure if I grasp pitch in terms of inches as I don't know how degrees for rotation calculates out to inches -- when I think of degrees, I think of it in degrees.

That said: Static propeller thrust, if this formula works right would be
0.00000000000283 * rpm^2 * Prop Diameter^4 * Air Density/29.92

I'm not sure what density I should use in this case... there's several units of measure one could use.

Are there any tables that include spanwise efficiency or zero lift drag coefficients for WWII aircraft designs?

There are many but none that I know of save two (an NACA and RAF table) with more than 10 or 12. All CDo related and most scale model wind tunnel values
