Euler’s equation integrated along a streamline results in Bernoulli’s equation provided the flow is:
(A) Incompressible, inviscid, steady, in an inertial reference frame
(B) Constant density, steady, along a streamline, in an inertial reference frame
(C) Incompressible, steady, along a streamline, in an inertial reference frame
(D) Constant density, steady, along a streamline, inviscid, in an inertial reference frame
(D) Constant density, steady, along a streamline, inviscid, in an inertial reference frame
Remember, constant density is more restrictive than incompressible. To move the density ? outside the integral symbol requires that ? = const.
