Theoretical flow rate equation
WebbThe actual flow rate through a venturi tube is seldom equal to the theoretical flow rate of an ideal fluid and usually turns out to be less than the theoretical flow rate. In order to account for this difference, a discharge coefficient C is introduced to obtain the final volumetric flow rate equation for an incompressible fluid flowing through a venturi tube … Webb5 mars 2024 · For each step, determine the flow rate by timed collection. Close the flow control valve, and turn off the pump. The pressure difference measured by the differential pressure gauge can be converted to an equivalent head loss (h L) by using the conversion ratio: 1 bar = 10.2 m water Low Flow Rate Experiment

Webb2 okt. 2015 · 1 Answer Sorted by: 1 The transition from Hagen-Poiseuille to Darcy-Weisbach behaviour happens when the flow regime switches from laminar to turbulent. Note that the DW equation has a fudge factor that describes the energy loss due to turbulence. This friction factor varies with flow rate.

WebbAnalysis of the flow line in Figure 1 shows that the water flow has diffluent rates in the horizontal and vertical directions and belongs to the plane two-dimensional flow. If the Dupuit assumption can be introduced and the vertical diffluent rate is neglected, the calculation can be simplified to a one-dimensional flow calculation in the x direction [ 32 ].
