Hi All

Could any one please tell me about how to find the volume of water in the pipe with respecticve of pise size.

I know it can be calculated through the formula :3.14 x R2 x H... The result is in 'cubic inches'.

Alternatevely,If you can suggest any other way to find out the volume in 'litres'

Please indicate the answer with the referred standard if any.

Thanks

This should help:
1 liter = 61.0237441 cubic inches

To be really, really picky, it does depend on pressure and density. What you can ask without a problem is what is the volume of a pipe having X dimensions.

The volume of water at the standard temperature and pressure willl be different, bu that's getting really picky.

With water, you can use 1 CC is 1 ml at atmospheric temperature and pressure and go from there. 1 CC also weighs 1 gram since the density is 1 gm/cc.

If you had water at 80 C and then let it out of the pipe and let it cool to 25 C, the volume at 25 C will be different.

Sometimes it matters, usually it doesn't.

If I remember, when it freezes, it expands 11%?

I know this is an old post but if you multiply diameter(in feet!) squared x .7854 x H' (in feet!)
gives you cubic feet.. There are 35.31 cubic feet in one cubic meter and 1000 litres in one cubic meter.
To convert diameter in inches to feet you divide by 12
