Flow factor cv
WebThe Cv tells you how to properly size your valve so it has minimal effect on the hydraulic efficiency you’ve engineered into your system. It is a number published by the valve … WebApr 3, 2024 · Lnewqban said: In practical terms, the coefficient is expressed only as a number. To expand/generalize, by definition a coefficient is a unitless multiplication factor, like a percentage. For example, a friction coefficient is a percentage/fraction of normal force "converted" to friction. Similarly, a flow coefficient is a fraction of velocity ...
