$m^{}=\underset{d{A}_{i}0}{lim}{\displaystyle \underset{i}{\overset{N}{}}}(V*hat(n))d{A}_i={\displaystyle \underset{A_s}{\overset{\phantom{}}{}}}(V*hat(n))dA$There is a cross section of the tube in Figure $3$ with lines denoting where the linear actuator is

allowed to place the static$$Pitot tube according to the software. On this drawing, map out

regions where you expect the fluid velocity can be represented by a single measurement

location. For example, the centermost measurement location should give a velocity that can

represent a circular region in the center of the tube.

Draw out shapes until the area is filled and find the areas corresponding to each. You do not

need to use each measurement location.
