Exam 12: Turbomachinery

Which of the following conditions is never a boundary condition in fluid mechanics?

Three measurements are made of the x-component velocity in the diffuser of an incompressible plane flow to be 32 m/s, 28 m/s and 20 m/s. The measurement points are Along the centerline of the symmetrical diffuser and are 4 cm apart. The y-component of the Velocity 2 cm above the centerline is approximated to be:

$\text {If the x-component of velocity \(u\) depends only on \(y\) in a plane incompressible flow, the }$$y \text {-component of velocity } v \text { is: }$

$\text {What four equations provide for the four unknowns u , v , w , p that are most often of interest in}$ $\text {fluid mechanics?}$
