Need 'Flow thru Annulus' calculator

Need 'Flow thru Annulus' calculator

(OP)

I need a spreadsheet (or formulas) to calculate and graph water flow thru an annulus formed by the gap between a circular orifice (square edged) surrounding a shaft.

Variables will be water pressure, orifice ID, orifice thickness (width), and shaft OD. Temperature will be constant (probably ~ 80F).

Ideally I'd like to make this a Map curve (3D) plotting flow vs diameter vs pressure but Flow vs Dia will be OK - (pressure as a constant).

I can dig thru Cameron’s but I figure somebody in our great group of Engineers probably already has one so I’ll post this in a couple forums.

THANKS!!
