1.414. x offset- Straight of 45's
Can you measure the distance from the corner to either end of the pipe ? The length of the pipe is (1.414) times that distance.
1.4142 will give you the travel piece C-C then you deduct for the fitting
whatever the offset is times it by 1.414 and this will give you your travel then just take off the centres of the 45's and you have your cut length....for instance if the offset is 12 inchs you multiply it by 1.414 you come up with 16.968..meaning 1 foot 4 inchs 15/16 just thought alittle clarity might help if the person was new in trade.

A 45 degree offset has a travel of 200mm. calculate the rise of the offset.
offset that are not situated 90 degree rather that are situated in any angle like 60 degree or 45 degree
The take off formula of a 45 degree elbow pipe, will depend on what the pipe is on. Sometimes a 45 degree pipe will need a 90 degree right angle turn to come off.
1.414. x offset- Straight of 45's
There are many types of rolling offsets. 2 common are rolling offset using 45 degree fittings and a rolling offset using any angle. using 45's Rise: elevation change roll: run of the pipe moving to the left or right Travel: the run of pipe to make the offset Simple formula Travel = SQRT((rise(squared) + Roll(squared) ) x 2) rise = 10" roll= 16" Travel=? travel= SQRT ( ((10 x 10) + (16 x 16)) x 2 ) travel= SQRT ( ((100) + (256)) x 2 ) travel= SQRT ( ( 356 ) x 2 ) travel= SQRT ( 712 ) Travel= 26.68333 or 26-11/16"
1.4142 will give the travel piece center to center
In all offsets to determine the travel you must multiply the set in inches by the cosecant of the angle required. For Example: The cosecant of 30 degrees is 2 The cosecant of 15 degrees is 3.86 The cosecant of 45 degrees is 1.414 Say your offset needed to travel 2 feet on a 15 degree angle. 24" x 3.86 = 92.64" or 7' 8 5/8" Say your offset needed to travel 2 feet on a 30 degree angle. 24" x 2 = 48" or 4' Say your offset needed to travel 2 feet on a 45 degree angle. 24" x 1.414 = 33.94 or 2' 9 15/16

formula for a 6" 45 degree lateral onto a 6" main
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.

it takes the same pressure if the vertical heights the same but since the 45 degree pipe would be longer it would create more flow restriction.
