Question

Problem 2 The following table represents two different data sets one for rectangyular weir, one for v-notch weir Determine a best-fit equation for the V-notch weir. You do not have to perform a formal regression analysis. Instead, use the add trendline option of your spreadsheet graphics. However, Evaluate each of the following equation types: (R-7) and (R-8) your data and therefore, the relationship must be expressed in a linear form before plotting. Eq. (R 7) represents a linear relation and Eq. (R-8) represents a power law. Note that for the power law relation you have to linearize the data first by taking a logarithm of the equation. I have solved for the rectangular weir and attached the print out of the spreadsheet and plots. You have to replicate this for the V-notch weir Question: Which equation is better for the data set? Why?

Explanation / Answer

For V-Notch weir,

It is very Interesting to see that the governing equation itself is power Law,

where k=2.49 and n=2.48

It is best fitted within the power Law instead of Linear
