I have the value of production waste (m3/day) and also the consumption (kwh/day) of some locations. You can see below that I have total information for locations 1 to 10. However, I don't have a consumption value for units 11 to 15. Therefore, I would like to know if it is possible to find these values, based on the consumption values I already have. It's important to note that they don't have to be exact values, but rather an estimate of what the value could be.

Ploting the available data, it seems natural to fit the data with a function of the form $g(p) = \alpha + \beta \sqrt p$. Using the least squares method, you see that best fit is $g(p)=0.7533 + 46.1266 \sqrt p$. In the graphic below you can see the data points (blue) and the fit (red).
However this was quite arbitrary... Maybe there are aspects of this specific situation that advise a different approach.
