Talk:Flow coefficient

AFAIK volumetric flow coefficient Cv is defined by volumetric flow / root of pressure drop. the formula with specific gravity refers to Cm - mass flow coefficient. — Preceding unsigned comment added by 132.68.22.156 (talk) 12:28, 21 June 2011 (UTC)

Kv definition and dimensional analysis
In order to be rigorous in term of dimensional analysis, there should be a factor added to the definition. For example factor :

$$k = 1 \sqrt{bar}$$

Alternatively:
 * 1) Kv unit could be given in cubic metres per hour and per square bar
 * 2) the factor could be chosen for Kv to be dimensionless
 * 3) a comment could be added to highlight the problem.

Best would be to do something consistent with the applicable standards or the industry practices, does someone knows more about that?

and also I think specific gravity is referred to instead of density (unit given)... a general clean-up on the units looks necessary
