When calculating bend allowances to determine the cut length of HDPE conduit or PVC pipe, one must calculate from the center line radius (CLR) of the finished, bent pipe. This radius will vary depending on the outside diameter of the tube, the wall thickness, and the angle at which the tube is to be bent. Elements of a Bend
Use the correct formula to calculate the circumference of the bend. For example, the formula used when making a 90˚ bend is: Circumference = (pi*2*r) / (360/90). When bending, take into account the ability of the material to bend and sustain the bend. It should also not break during the process or later in application DOB = Degree Of Bend. Length of tube in a bend = CLR X DOB X .01745 or, to put it another way: L = (R X .01745) x Z, L is the length, R is radius of the pipe bend, Z is the angle of the bend. Setback = radius X tangent ½ angle of bend. Circumference = 3.1416 X diameter What is the force required to accelerate an object with a mass of 20 kg from stationary to 3 m/s 2? F = m * a.
