Linear momentum balance equation

NettetA momentum balance can be written for the control volume shown in Fig. 2.6-3 which is somewhat similar to the overall mass-balance equation. Momentum, in contrast to mass and energy, is a vector quantity. The total linear momentum vector P of the total mass M of a moving fluid having a velocity of v is. Equation 2.8-1 . The term Mv is the ... NettetThe momentum equation (Eq. 4.2 ), an expression of Newton’s second law of motion, represents the transient force balance on the fluid within a slice of the pipeline cross-section. •. The left side, , is mass times acceleration per unit volume of fluid (there is a velocity change in time, , as well as a change as it moves in distance, ).

NettetLinear momentum is the vector quantity and defined as the product of the mass of an object, m, and its velocity, v. The letter ‘p’ is applied to express it and used as momentum for short. Please note that the body’s momentum is always in the same direction as its velocity vector. It’s a conserved quantity which means that the total ... NettetEnergy equation (8) is only a linear combination of continuity and momentum equations (5)&(7). It is not needed for solving the sound field. It is only used for energy balance analysis. With the isentropic relation, continuity equation (5) can be rewritten as: . (14) This is the equation for internal energy balance.
