Circumference = pi*diameter so diameter = circumference/pi = 40/pi = 12.7324 feet (to 4 dp)
It is: 12/pi = 3.8197 inches rounded to 4 decimal places
A circumference is 4
The circumference is 12.56 approximately
A circle with a 4-foot diameter has a circumference of about 12.57 feet.
Nominal pipe size 3/4" outside diamerter : 26.7 and thickness is 2.9 mm at sch 40
16 gauge pipe refers to the wall thickness of the pipe exclusive of its diameter.It is 0.064 inches thick, this is a steel wire gauge measurement.Pipes are typically sold by schedule numbers. A wall thickness of 0.064 inches would correspond to pipe schedule 40 for 1/8" diameter pipe (0.068"), schedule 10 for 1/4" and 3/8" pipe (0.065") and schedule 5 for pipe diameters 1/2" to 2" (0.065"). Over 2" diameter pipe, schedule 5 (the smallest wall thickness) is thicker than 16 gauge steel.
Schedule 40 welded carbon steel pipe (black) is rated at a working pressure of 150 psi. It should be printed on it. Schedule 80 welded is rated at 300 psi. If U want higher rated piping you must use seamless (not welded) pipe. Hope this helps!
The wall thickness of 4" Sch 40 pipe is 0.237 inches.The outer diameter is 4.5 inches and the inner diameter is 4.026 inches.
Circumference = pi*diameter so diameter = circumference/pi = 40/pi = 12.7324 feet (to 4 dp)
A 770 Greenlee hydraulic pipe bender bend is used for rigid steel conduit from 2" to 4".
4inch Schedule L Copper pipe weights 5.38 lbs/ft.
"4 inch" would usually refer to the diameter in such cases. You can multiply that by pi (which is about 3.1416) to get the circumference.

no 2" is enough if it's just the washing machine.
The pipe will have an outside diameter of 1.5+.25+.25 = 2". A pipe with an outside diameter of 2" has an outside circumference of 2"*Pi. 2"*3.142 ~= 6.284" or about 6 1/4"
what grade would a 4" drain pipe 40 feet long require
