17. in a turbine, a device used for mixing, the power required depends on the size and shape of the impeller. in the lab, we have collected the following data: 1 diameter (d) [ft] 0.5 0.75 1.5 2 2.25 2.5 2.75 power (p) [hp] 0.004 0.04 0.13 0.65 3 8 18 22 a. create a proper plot of the power (p, ordinate) versus the diameter (d) assuming the data are experimental. b. use polyfit to determine a power relationship for the data set and graph the resulting trendline along with the experimental data.
