Question
In Example 5.10 in your book and discussed in class, one of the three Pi groups found is Reynolds number. The final power law function in the book is One can see that the Reynolds number Pi group has an exponent of 1.75. From where does this exponent come? O A. It is the slope of the line upon graphing the pi groups on a semi-log scale on the y-axis O B. It is the slope of the line upon graphing the pi groups on a log-log scale. O C. It is the slope of the line upon graphing the pi groups on a semi-log scale on the x-axis O D. It is the slope of the line upon graphing the pi groups on a linear scale.Explanation / Answer
Option B))
Because a log-log plot results in a line to fit the equation exactly to the given points. In a linear graph you get a curve which equation cannot be fitted easily,
