Final Answer:
According to the given relation, when \(V_{\text{ref}}\) is 10, \(V_{\text{rot}}\) is approximately 4.
Step-by-step explanation:
The information provided suggests a relation between \(V_{\text{rot}}\) (rotational velocity) and \(V_{\text{ref}}\) (reference velocity) in the form of an approximate equation:
\[ V_{\text{rot}} = V_{\text{ref}} - 6 \]
This equation indicates that the rotational velocity (\(V_{\text{rot}}\)) is approximately equal to the reference velocity (\(V_{\text{ref}}\)) minus 6.
If you have specific values for \(V_{\text{ref}}\), you can use this equation to find the corresponding \(V_{\text{rot}}\) by substituting the values into the equation.
For example, if \(V_{\text{ref}}\) is 10, then:
\[ V_{\text{rot}} = 10 - 6 = 4 \]
So, according to the given relation, when \(V_{\text{ref}}\) is 10, \(V_{\text{rot}}\) is approximately 4.
