Calculation of the flow coefficient for control valves
Thread Content
In the figure below, the flow equation Q is used to introduce the concept of the flow coefficient C. However, why is the unit of the flow area A taken as cm2 instead of m2 in the calculation of C? I would appreciate it if the teacher could explain this.
It’s just a matter of changing the units to those commonly used in engineering; you can also use the International System of Units, and the results will be the same
