21. By what age do children develop an understanding of conservation of mass ? Preceding contribs) 22. Conservation of mass is trivially true.23. Before introducing this constraint, we must apply the conservation of mass to generate the necessary relations. 24. Conservation of mass requires that the amount of air entering and exiting a turbine must be equal.25. Under this condition, conservation of mass implies that the vertical velocity of the fluid is small. 26. Once understood, the conservation of mass was of great importance in progressing from alchemy to modern chemistry. 27. :" Antoine Lavoisier's theory of conservation of mass " has nothing to do with it. 28. The full Stokes equations also includes an equation for the conservation of mass , commonly written in the form: 29. This extra equation is the continuity equation for incompressible fluids that describes the conservation of mass of the fluid: 30. :: : : Of course, even with a chemical change, the conservation of mass still applies.
