Euler’s Equation:

• First, dz=0 no elevation variation

If dpɬ, pressure increases as fluid flows downstream

then dVɘ, velocity decreases due to the adverse pressure gradient

and vice versa.

• If dp=0, no external pressure gradient

If dzɘ, fluid flows to a lower point, dVɬ, its velocity increases

and vice versa

• If dV=0, no flow

If dzɘ, into the lower elevation inside the static fluid system,

dpɬ, pressure increases
