COOL CALCULATORS
"Resources, tools and basic information for engineering and design of technical applications" at The Engineering Toolbox include formulas and online calculators for determining the flow coefficients (Cy) and flow factors (Kv) of liquids, steam and gases. With the flow coefficient, flow capacities of valves at different sizes, types and manufacturers can be compared, and estimated Cv values can be used to select the correct valve.

CHARACTERISTICS AND THEORY
The Flowmetering webpage introduces fluid characteristics and flow theory (including Bernoulli's theorem and Reynolds' numbers) to provide basic metering theory and techniques. Different meter types, instrumentation and installation practices are also discussed. Topics include fluids and flow, principles of flowmetering, types if steam flowmeters, instrumentation and installation.
