COMPARISON BETWEEN THE FLOAT METHOD AND THE HYDROMETRIC SHEET FOR ESTIMATION OF FREE FLOW CONDUITS
Abstract
The objective of this work was to produce and calibrate a windmill, and to compare the results obtained with the float technique, determining the flow rate and mean flow velocity of the Caveirinha stream, located in the city of Goiânia, Goiás. Results between the methods of measurement of velocities and the flow in Caveirinha stream, the percentage difference of the average speed between the two methods used was of 54.55% and of 51% in their flows. Therefore, the windlass produced guarantees reliable results, thus contributing to better management of water resources. However, there is a great need to compare it with the properly calibrated conventional hydrometric windlass establishing a direct relationship in the results.
