WebThe continuity equation represents a conservation law, hence the name. Indeed, integrating the continuity equation over a volume V{\displaystyle V}, large enough to have no net currents through its surface, leads to the conservation law ∂∂tQ=0,{\displaystyle {\frac {\partial }{\partial t}}Q=0\;,}
Webas per the continuity equation A1vi = A2v2 it says that the value of Avhas a constant value throughout the pipe. So, if the area, A of a section of pipe decreases, the speed, v of the liquid there must increase so that the product, Av remains the same. spracheingabe openofficeWebApr 10, 2024 · So, ρ1 = ρ2. Applying this to Equation 4; it can be written as: A1v1 = A2v2. The generalized form of this equation is: A v = constant. Now, let's consider R as the volume flow rate, hence the equation can be expressed as: R = A v = constant.
