WebThe Navier-Stokes equations represent the partial differential equations that explain the flow phenomenon of a viscous, incompressible fluid. They are based on the principle of … WebIn physics and chemistry, the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time. This law, first proposed and tested by Émilie du Châtelet, means that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another. theta in macbook shortcut
