The multiplier for a 45 degree bend is 1.4142 (rounded off to 1.4) times the height of the offset. All offset multipliers are the cosecant of the angle. (inverse of the sine of the angle). However, 45 degree offsets are very difficult to pull wire through and should be avoided. Always bend your EMT to the shallowest angle you can for the distance you have to do it in.
To calculate the multiplier for a 45 percent offset, you can use the formula: Multiplier = 1 / (1 - Offset). In this case, the offset is 0.45, so the calculation would be: Multiplier = 1 / (1 - 0.45) = 1 / 0.55, which equals approximately 1.818. Therefore, the multiplier for a 45 percent offset is about 1.818.
30 degree bends -as in a conduit offset- create a 3-4-5 right triangle extrapolating the "3" of the triangle to your 7" offset should result in a shrinkage of approx 2- 1/3 inches. Sinceconduit bends are curved and not exact angles this may not be accurateenough to pre-cut and thread and then bend. I assume that is why you were asking. I also assume you are talking large size conduit. I will leave the 22-1/2 degree question to you.

Use these numbers when bending offsets: 10 degree bends, multiply the depth of the offset by 6 this will give you the distance between bends. For 20 degree multiply by 2.6, for 30 degree multiply by 2, for 45 degree multiply by 1.4, for 60 degree multiply by 1.2. I use 30 degree bends for all of my offsets, just because its easier to do the math. So your answer would be 24 inches between bends. I have come to the conclusion anybody can bend conduit, its the measuring and marking that requires skill.

Neither is correct unless you're using the plural form of degree. Then only "How many degrees" would be correct.Here is an example sentence to show the incorrectness of the first and second phrase.Please tell me how much degree is needed to offset the ratio.Please tell me how many degree is needed to offset the ratio.The correct sentence would be:Please tell me how many degrees are needed to offset the ratio.

When offsetting conduit around an I-beam, a two-bend offset is typically used. This method involves making two bends in the conduit to create a gradual change in direction, allowing the conduit to clear the I-beam without creating sharp angles that could compromise the integrity of the installation. The bends are usually made at equal angles, ensuring a smooth transition.
To bend 1-inch steel conduit, you would typically use a hydraulic or manual conduit bender specifically designed for EMT (Electrical Metallic Tubing) or rigid conduit. A popular choice is a 1-inch EMT conduit bender, which features a 30-degree bend mark and a sturdy frame for leverage. Hydraulic benders are often preferred for larger jobs due to their ease of use and ability to create precise bends without damaging the conduit. Always ensure the bender is compatible with the type of conduit you are working with.
The multiplier you would use is 1000.1.9 km x 1000 = 1900 m
Quite simply, no. The Spending multiplier, even on government spending, will always have a value of greater than one. It really is self-evident; for that money to be subjected to a multiplier, it must be circulating multiple times, therefore the first circulation (the initial spending) would result in a multiplier of one, and subsequent spends would increase the multiplier further
