The control volume approach in fluid mechanics relies upon the conservation of energy, momentum and angular momentum. However, open channel flows are typically related to only conservation of energy and momentum. Thus, for flows of non-uniform velocity and non-hydrostatic pressure distributions, the ...
In general, when solving fluid mechanics problems, one should use all available equations in order to derive as much information as possible about the flow. For example, consistent with the approximation of the energy equation we can also apply the momentum and continuity equations Forces...
A one-dimensional momentum conservation equation for a straight jet driven by an electrical field is developed. It is presented in terms of a stress component, which can be applied to any constitutive relation of fluids. The only assumption is that the fluid is incompressible. The results indicat...

(2.23) In writing the equations of fluid mechanics in a general setting, Lie derivatives naturally emerge that express transport of quantities. For example in the Euler equation (3.1a) below, a Lie derivative Luν appears to express transport of momentum, in place of the traditional u · ...
Equation for Angular Momentum As mentioned in the previous section, all symmetrical objects rotating about a fixed axis have angular momentum. It is expressed as L=Iω, where, L is the angular momentum in kg m²/s; I is the moment of inertia in kg m²; and ω is the angular veloc...
