EXPERIMENTAL DEMONSTRATION OF THE ENERGY CONSERVATION OF WATER BY APPLYING THE BERNOULLI PRINCIPLE

Abstract

Bernoulli's principle is fundamental in hydrodynamics, its application in mechanical engineering is important for the calculation of the effective head of pumps and fans; In fluid mechanics, the conservation of energy in a non-viscous compressible fluid was established in 1738 by the Swiss mathematician and scientist Daniel Bernoulli in his book Hydrodynamics. In this context, an experimental investigation was carried out to experimentally analyze and demonstrate the conservation of water energy by applying the Bernoulli principle in a technical laboratory test; This research is of an experimental application type and for its quantitative approach in its development, the methodology of the Experimental Technical Test in Engineering was used, which involves the preparation and execution of the test, using the basic water supply modules and the principle of water module. Bernoulli consisting of equipment to measure the flow and pressure of water flow with Venturi and Pitot pipes. In preparation for the test, the basic module on which the Bernoulli module was mounted was put into operation. preliminary tests to acclimatize ourselves with the operation of the experimental module and, during the execution, experimental parameters of flow, velocity, static pressure and total pressure were measured at six points of the Venturi tube whose areas progressively decrease and increase for experimental demonstration. The results obtained by replacing the Bernoulli equation showed that the total energy of the water flow in each of the six different areas along the Venturi tube remains constant with reliable experimental precision in the range of 0.11576 to 0.12373 column meters. of water; also demonstrating in the area of ​​higher speed the water will have lower pressure and vice versa.
