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.
