tank's drain size
(OP)
Hi,there:
I am wondering that is there any general guide on how to decide a low pressure tank's drain size based on the tank's design data, such as height, diameter and capacity?
Thanks.

RE: tank's drain size
Flow rate is controlled by head pressure, including any pressure in the vapor space, fluid properties, drain opening geometry, and drain fittings and piping.
Crane Tech Paper 410 is a good reference for starting your calcs.

RE: tank's drain size
Such factors are steam-out purposes, size of the tank, material stored..etc
I have seen various drain sizes as 2" for small tanks and 6" for large tanks
Hope this would help
cheers

My opinion is 2" for a small tank is adequate, while 4" is reasonable for most purposes on larger tanks.

RE: tank's drain size
If you expect buildup on the bottom of the tank (e.g wax, sludge, sand, etc.) and the tank needs to be pumped/vacumed out, then the drain size may need to be larger.
