Formula - assumptions
tan(angle) = rise / run → angle = 36.87°
Practical angle = 36.86989764584402° (multiplier 1.67)
Distance between bends = rise / sin(angle) = 18.375 / 0.600 = 30.625 in
Shrink (conduit length compensation) ≈ 3.675 in
  (from standard field shrink table: 0.2000 in per inch of rise)

All calculations are based on center-to-center of conduit.
