It is known since long that hydrodynamic flow in the directions of an external gravitational force and gradient of temperature are related to each other. We consider generalizations to the cases of higher orders in hydrodynamic expansion and/or to higher orders in acceleration. We demonstrate in particular that the vortical effect in presence of gravity is reproduced via the equivalence principle while usually it is ascribed to the so called gravimagnetic anomaly. A crucial point is existence of extra conservation laws in case of non-dissipative fluids. We comment also on the duality between evaluation of various matrix elements in case of equilibrium physics and motion in external gravitational force.
