What is oblique offset in surveying?
offset that are not situated 90 degree rather that are situated in any angle like 60 degree or 45 degree
What multiplier would be used for EMT conduit to make a 45 degree offset bead?
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.
What is the take off formula off 45 degree elbow pipe?
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.
How do you find out the lenght of a piece of a pipe on a 45 degree angle?
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.
What are fittings used in plumbing?
Couplings, 45's, 90's, tees, male iron pipe, female iron pipe, reducers........all for joining or directing pipes
How do you figure a 7 foot horizontal rolling offset?
A rolling offset is generally an offset requiring a change in 2 directions. Eg. A horizontal offset and a vertical change in elevation. There is additional information required to answer the question. What is the angle of the fittings being used for offset? 15 deg. 30. 45? What is the change in elevation? If this is a flat (no change in elevation offset) using 45 deg., the offset dimension (7') is multiplied by 1.4142 which is the secant and cosecant of 45 deg. The result 7 ' x 1.4142 = 9'-10 13/16" Again, this result is for a flat run of pipe. If we have a rolling offset with a change in elevation of say 1'. We can use the Pythagorean theorem (A2 +B2 = C2) The result would be (1')2 + (9'-10 13/16")2 = 98.99812 sq. ft. The square root of 98.99812 is 9'-11 3/8"
Calculate 45 degree offset when the travel is known?
A 45 degree offset has a travel of 200mm. calculate the rise of the offset.
What is the rise in plumbing?
The hypotenuse of the 45 deg offset calculated by the constant 1.4142 The rise could also be the slang use of pitch from the point of discharge back to the highest point
What is the formula for a rolling offset with 2 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"
What an 8 inch 90 degree pipe fitting take off when rolled 45 degrees?
90 degree angle rolled on a 45
What is the pipe fitting formula for 30 degree elbow?
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
How much more pressure does it take to push water up a vertical pipe than if the pipe is on a 45 degree angle?
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.
