a. Determine the dimensions of the small tank and impeller,using geometric similarity. (10 points) (Hint: Youcan assume the same height-to-diameter ratios)
b. What would be the required rotational speed of the impellerin the small tank if we want to maintainconstant kLa value?(15 points) (Hint: You can use the EmpiricalMethod for kLa; i.e., eq.[67])
