WebThe first impact that may come to mind is a larger orifice – and it’s correct. The size of the orifice can benefit flow through and directly relates to the volume of your valve. However … WebOct 28, 2024 · Increased viscosity can reduce the amount of slip, which can result in increased output flow per shaft revolution, and an increase the volumetric efficiency of …
WebMay 26, 2005 · olynyk, in my opinion, Cv is not derived from any equation in particular, but empirically defined (and measured) as "the flow rate which flows through a valve at a given travel referred to 1 psi of dp across the valve and water at room temperature"; then the definition must be taken "as is" and considered for its practical value, i.e. because it … WebThe effect of specific gravity on gases is similar. For exam ple, the specific gravity of hydrogen is 93% lower than that of air, but it changes flow by just 74%. Carbon dioxide has a specific gravity 53% higher than that of air, yet it changes flow by only 24%.
WebValves are tested by running water through it before publishing the Cv value. It can be assumed that the tests are done with water (unless otherwise noted), using a specific gravity of 1.0, 1.2 centistoke viscosity, and a standard temperature of 60 degrees Fahrenheit.
