The Hydraulic Diameter of an Annulus calculator computes the hydraulic diameter based on the inner and outer diameter of the annulus.

INSTRUCTIONS: Choose units and enter the following:

(o) Outer diameter
(i) Inner diameter

Hydraulic Diameter (hd): The diameter is returned in meters. However, this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The formula for the hydraulic diameter of an annulus is:

hd = o - i

where:

hd = hydraulic diameter of an annulus
o = outer diameter
i = inner diameter
