Question 5 Could we use the following equation to estimate t

Question 5: Could we use the following equation to estimate the shear rate? shear rate = 8 x velocity / diameter; where we would use the mean velocity calculated from the data? and why are we limited to estimating the shear rate at the wall?

Question 5 is yes or no question and you need to explain the reason and tell why we are limited to estimating the shear rate at the wall using the given equation. And there is a data table that shows the velocity and location of the velocity in the vessel.

Solution
