This article summarizes equations in the theory of fluid mechanics. WebNov 15, 2024 · Ω × ( Ω × r) = − 1 ρ ∇ P + g. . Because of rotational symmetry, the pressure is P = P ( r, z). From here, Euler's equation ( r and z components) give you the pressure and allow you to determine the paraboloidal shape of the fluid surface. Then, to get the fluid velocity in the lab frame, you can use the relation.
