Flowing gas energy eequation convection gas
Webequations of fluid dynamics—the continuity, momentum and energy equations. These equations speak physics. They are the mathematical statements of three fun-damental … WebThe internal energy of an ideal gas is proportional to the temperature, so if the temperature is kept fixed the internal energy does not change. The first law, which deals with changes in the internal energy, thus becomes 0 = Q - W, so Q = W.
