In the elementary form of the continuity equation for mass, in hydrodynamics: In elementary classical mechanics, mass flow rate is encountered when dealing with objects of variable mass, such as a rocket ejecting spent fuel. Often, descriptions of such objects erroneously invoke Newton's second law F =d(mv)/dt by treating both the mass m and the velocity v as time-dependent and then applying the derivative product rule. A correct description of suc… Web9 de abr. de 2024 · The mass flow rate is the movement of mass per unit time. The mass flow rate can be expressed as m and the mass flow can be calculated in terms of kg/s. Mass flow rate equation m = ρVA Here, m denoted the mass flow rate ρ denotes the density of the liquid. V denotes the velocity of the liquid A denotes the cross-sectional area.
