SUMMARY
The correct formula for calculating shear stress (tau) is derived as -d(p+yz)/ds (r/2), which differs from the user's initial calculation of (-dp/ds -ydz/ds)(r/2). The user expresses concern about the derivation process and questions the accuracy of the book's formula. The discussion highlights the importance of understanding the derivation steps to ensure accurate application of the shear stress formula in fluid mechanics.
