A 4 inch drill pipe torque is used for fishing in small casing.
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.
for 4 inch and ahove 1.5 multiple with pipe size

Please Calculate the weight per fit of G.I. pipe

Every time! lol Seriously a 10-inch pipe is 5/4 of an 8-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.

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.
