So, to draw a 30° angle, construct a 60° angle and then bisect it. First, follow the steps above to construct your 60° angle. Bisect the 60° angle with your drawing compass, like this: Without changing the compass, relocate the needle arm to one of the points on the rays. Roof Angle (degrees) Slope Factor (multiplier) Valley and Hip Factor (multiplier) 1:12 pitch 4.76° 1.0035 1.4167 2:12 pitch 9.46° 1.0138 1.4240 3:12 pitch 14.04° 1.0308 1.4362 4:12 pitch 18.43° 1.0541 1.4530 5:12 pitch 22.62° 1.0833The friction loss for each bend is: Δ p f f = ζ x 1 2 ρ w x 2 = 673.2 P a. The total friction loss for the 10 bends is. Δ p f f = 10 ⋅ 673.2 P a = 6732 P a = 0.067 B a r. Step 6 Calculate the entire friction loss for the pipe including the fittings in this case only 90° bends but normally it also includes valves, reducers, equipment etc.I always mark my hand benders with the center marks for 5, 10, 15 and 30 degrees. This makes bending faster, more neat, and easier to match multiple runs. On my usual 3/4 ENT bender, a 2 inch offset on 30 degrees is the minimum offset. I would normally bend any 3/4 EMT offset, less than 3 inches, on 15 degree or less bends.The height of the stub, or accurate stub, is the distance from the top of the conduit to the bottom of the 90-degree bend. The height of the stub is determined by measuring the length of the conduit from the center to the center. You can also bend a 3-point saddle with a hand bender. For 15-degree bends, multiply the length by 3.9.
