SUMMARY
The discussion centers on the calculation of volume flow rate through an area element, specifically addressing the confusion between using ucos(theta)dA and usin(theta)dA. The author clarifies that dA lies in the yz plane, making u' = ucos(theta) the correct representation for flow parallel to dA. This distinction is crucial for accurately determining the flow rate in fluid dynamics problems.
