Flow Rate of Fluids in Pipes The quantity of fluid that will be discharged through a hose depends on the pressure applied at the feed end, the hose length and bore diameter. The surface character of the bore, the number, and shape of bends incorporated in the run of the hose also influe...
In a microfluidic system, viscous forces predominate over inertial forces, leading to laminar flow behavior and simplification of the Navier-Stockes equations. In this context, the flow rate is directly linked to pressure and flow resistance. The relationship is given by the following formula: To ...
Flow rate, often measured in terms of volume or mass per unit time, is a critical parameter in industrial processes. It measures the speed at which fluids move through pipelines, valves, and other system components. Controlling and maintaining an optimal flow rate is essential for process stabili...
Flow Rate Formula The flow rate of a fluid can be calculated using the volumetric flow rate equation: Q = A × v Thus, the volume flow rateQis equal to the cross-sectional area of the pipeAtimes the velocity of the fluidv.[2] ...

From the tangential velocity formula (u=πDN/60) and the equation we can deduct Eq. (6.31). (6.31)D∝HN As the flow rate is the product of the cross-sectional area and the water velocity, so from Eq. (6.11), we can deduct the following relation of Eq. (6.32). (6.32)Q∝Av By...
An experimental study of two-phase flow pressure drop using R-134a is conducted on three types of different surface wettability microchannels with superhydrophilic (contact angle of 0°), hydrophilic (contact angle of 43°) and common (contact angle of 70°, unmodified) surfaces, all with a hyd...
