Liquid flow rate in a partially filled pipe.
Liquid flow rate in a partially filled pipe.
(OP)
Dear All,
I'm looking for some advice on the correct formula to use for liquid flow rate caluations in a partially filled pipe.
I have used this formula.
Mass flow rate = (density)^2 g (with of cord) (height of film in pipe)^3 sin (fall angle) / (3 * visocity)
And adapted it to assume a circular pipe. I'm looking at a header which accumualates liquid - can anyone advise or give me a reference for a more suitable formula. I've check most books and not found much.

it just may be of help.
Hydraulic formulas for flow in channels can be found in Kempe's Engineers Year-Book (1987) (Morgan-Grampian) pages B1/19+.
Good luck.
