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… WebIn laminar flow, 16 Re f = . In turbulent flow we can use either the Colebrook or the Zigrang-Sylvester Equation, depending on the problem.
