SUMMARY
The modulus of speed (u) in fluid mechanics is calculated using the equation u = (-2/r)e_r + (2/r)e_theta. The terms e_r and e_theta represent unit vectors in the radial and angular directions, respectively, in plane polar coordinates. The user attempted to simplify the expression to square root 8/r, asserting that the unit vectors do not affect the modulus. Verification of this calculation is necessary to confirm its accuracy.
