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:

$Q=k+ny$

and

$Q=k{y}^n$

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?
