Calculation

[nr1990]

How can I calculate the pipe weight? Is the diameter of the pipe is 1100mm.

That's one big suction line.

its a storage pipe tank or somthing...

[icecube51]

use the same formula as for a pipe of 3/8" or 1/2" and so on.
what is it you want to now? the inner volume per meter of gas or liquid?
the amount of gas/liquid thats going throu the pipe per second?
define youre question so whe are able to help you out.

Empty pipe:
pi*d*t times density of the material...watch your units!

Volume of contents: pi*d*d/4*length

To work the weight of the contents: you need to know its density at the highest pressure you can expect; and if that implies it could be both liquid and gas (refrigerant in cold surroundings;; pumped recirc arrangement or ?) you will have to figure how much of the frig charge could reasonably end up in this pipe....

1100 mm? Is an odd size
