Does anyone have the formula for increasing pipe size by double will increase capacity by 4?

How to find the area of a circle (PIPE)
The formula that I have always used to find the area of a circle or a pipe is:
"Diameter squared X .7854"
based on this formula you come VERY close to quadrupling the area when the pipe size is doubled0 -
Pipe sizing
B & G has a convenient circular "System Syzer" calculator. Besides pipe sizing it will give you the gpm for a specified Delta T and BTU. As for doubling the pipe size and 4X the capacity, it don'ty work that way!
IE:
1 inch copper with 2 Ft loss per 100ft: 5 gpm, 2 inch is 30 and 4 inch is 200 gpm.

Capacity Vs. Flow rates
Respectfully
The question posed by the "Wiz" was in reference to pipe capacity, not flow rates.
Capacity is the cubic content or volume of a pipe, container or vessel in a static state.
The formula to find the "CAPACITY" or volume of a cylinder (pipe) is:
Diameter squared X .7854 X length = volume.
It ain't opinion, it's mathematics.0 -
I like Pi
I still use the pi method. must have been all that geometry in school r x r x 3.14= area (r+r) x 3.14= circumference. Of course it adds the step of dividing the diameter by 2 and to be accurate you need to know the schedule of the pipe. Is it L, M, or K copper or is it schedule 40, 80, or 120 I.P.S?Cost is what you spend , value is what you get.
