3–7 ■ FLUIDS IN RIGID-BODY MOTION
Pressure at a given point has the
same magnitude in all directions, and
thus it is a scalar function.
In this section we obtain relations for
the variation of pressure in fluids
moving like a solid body with or
without acceleration in the absence of
any shear stresses (i.e., no motion
between fluid layers relative to each
other).
