Because the flow inside the channel is in a very laminar condition, the Poiseuille equation can be used to relate the force fall on the volumetric flow level. A next laser positioned further more downstream of the initial laser repeats this method having a 2nd photodetector, along with the velocity from the flowing https://gasmetertestbench91234.bcbloggers.com/29325785/the-definitive-guide-to-water-meter-test-bench
