In this video, by means of the square method, we measure the volumetric flow that is coming out of a pipe or tube, we also review through an example how long a reservoir will be filled with water, additionally by reading the operating curve or characteristic curve of a pump and making estimates of the total dynamic load we can also calculate the flow rate that is coming out of a pipe, this calculation can be applied in irrigation or agriculture, as well as in water treatment applications, the volumetric flow rate involves the volume per unit of time and the best known units are GPM, m3/h, lpm and lps, we see the conversion factor for the two best known flow units and we also convert from psi to meters of water column to Determine the operating point of the centrifugal pump.
The square method is developed by measuring the parabola generated by gravity on a flow that exits through a horizontal pipe.
In reading the performance curve of a pump, a pressure gauge is an essential instrument in the absence of a venturi or electromagnetic flowmeter.
