Hi Folks,
The Bernouli equation is that
P + (1/2)mv^2 + mgh
where m is the mass per unit volume, is constant along a streamline of a
viscosity-less incompressible fluid undergoing laminar flow. Does
thinking of the pressure P as some kind of pressure-energy density to be
encouraged, or does is lead to later difficulties? Since the fluid is
incompressible, it is clear that P does not represent work per unit
done in compressing the fluid.
