What does flow coefficient mean?

What does flow coefficient mean?

The flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow. It describes the relationship between the pressure drop across an orifice valve or other assembly and the corresponding flow rate.

Why is the coefficient of discharge less than 1?

Plug in a coefficient for energy losses through turbulence and you have your formula. But you can see indeed that your coefficient can never be greater than one, because that would mean that you end up with more energy than you started with.

What does a high flow coefficient mean?

High flow coefficient of a device such as restriction orifice or a control valve indicates low resistance to the passage of flow. Similarly low coefficient indicates higher resistance to the passage of flow and high pressure drop for a given flow.

How do you find a sample range?

The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6. It is that simple!

How do you calculate a range?

Summary: The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.

Why is the range important?

An important use of statistics is to measure variability or the spread ofdata. The range, another measure ofspread, is simply the difference between the largest and smallest data values. The range is the simplest measure of variability to compute. The standard deviation can be an effective tool for teachers.
