Water's surface tension is approximately 72.8 millinewtons per meter at 20°C, a high value that directly explains the science behind waterdrops. This remarkable property, driven by hydrogen bonds, is at the core of how water behaves in droplets and on various surfaces.

According to the principle of continuity, the flow rate of an incompressible fluid remains constant throughout a pipeline. This constant measurement, representing the volume of fluid passing through a point per unit of time, is fundamental in many engineering and industrial applications. Determining this figure is essential, so it is necessary to know how to calculate the flow rate of a tube.
