Re How to calculate the flat form of a flight of screw conveyor Then the inside developed diamater, B = square root of PI d 2 P 2 - Value of PI = 3,1415926, So the developed inside radius of the flight will be r = R-b =>b=R-r b/r= r-R /R - 1º step R/r=A/B R-r /r= A-B /B - 2º step consider that R is the developed outise radius...
