Flow rate equation cross sectional area
Volumetric flow rate can also be defined by: where: • v = flow velocity • A = cross-sectional vector area/surface The above equation is only true for flat, plane cross-sections. In general, including curved surfac… WebOne important difference between Hagen–Poiseuille equation and Ohm’s law is that, unlike the electrical resistance, the fluidic resistance is not inversely proportional to the cross-sectional area π R 2, but to π R 4 (for Ohm’s law, see Chapter 4, Section 4.3.1).
