Have you ever wondered what it means to calculate the flow rate of a valve? It may sound like an intimidating concept, but understanding a few basic concepts can help give you a better grasp on how this important calculation works. The official business definition of Valve Flow Calculation is the process of calculating the fluid velocity, pressure drop, and mass flow rate of various fluids passing through a valve system. This calculation helps engineers to accurately make decisions regarding the size of valves, as well as their placement within a system. With a scientific approach, valve flow calculation can be complex yet still provide simple and effective results.
