It is not possible to provide a sensible answer since weight depends on the volume of the object. For a cylindrical object it is necessary to have three measures: outer diameter, inner diameter and length.
Instead of the diameters you can have radii or circumference, and instead of two diameters you can have one diameter and the thickness. In any case, three measures are required. Only one is given in the question and there is no indication as to what it refers to!
Please Calculate the weight per fit of G.I. pipe
The weight of the pipe will depend on its volume, The volume in turn, will depend oninner radius or diameter,outer radius or diameter,length.Only one of these is given.
A 4 inch drill pipe torque is used for fishing in small casing.
Every time! lol Seriously a 10-inch pipe is 5/4 of an 8-inch pipe
By calculating the areas of circles with diameters 6 and 4 and comparing those: pi3^2=pi9 pi2^2=pi4 pi9/pi4=9/4=2.25 So the 6 inch pipe holds 2.25 times as much as the 4 inch pipe.
Pipe size refers to the diameter of the pipe (in inch).
A 4-inch Schedule L copper pipe weighs approximately 9.52 pounds per foot.
1/2 inch for 1/2 inch pipe.
for 4 inch and ahove 1.5 multiple with pipe size
The volume of water in a 4-inch diameter, 1-foot section of pipe is 0.6528 gallons of water.
It is based on the flow area, which is proportional to the square of the diameter. 2 squared = 4. 4 squared = 16. So, the 4 inch pipe can take 16/4 = 4 times the volume of the 2 inch pipe. It might be less confusing if you had picked sizes other than 2 and 4. This is a rough calculation, since pipe inside diameters are not the same as nominal sizes, but close enough for most purposes.
