Estimación del Caudal de Descarga de un Tanque Abierto

Abstract

This paper proposes a methodology for determining the discharge coefficient of an open tank through the Torricelli equation for which is broken down into 4 chapters. The first chapter deals with topics such as the Torricelli equation from Bernoulli’s equation, assuming that Daniel Bernoulli first exhibited his work. It expresses the behavior of this equation by differential equations, adding other works based on the discharge coefficient and its relation to the change in height. Chapter 2 is Instrumentation Air Flow Meter with 922 which presents the instrument responsible for sensing the system behavior is briefly described their functions and powers as a justification to be used in this work. Later is Chapter 3 which shows the methods for interfacing between the differential pressure sensor and an array of pics programmed based on structured programming language C. Then there are demonstrations and corrections to the data sheet of the inverter gate with Schmitt Trigger Hysteresis MC14106B model, with the support of circuit simulation program ISIS OF PROTEUS. Finally comes the issue of results and discussion, showing a 2 experiments to show the relationship between height and the differential pressure of the tank and the second the change in height over time. It demonstrates the importance of the introduction of the discharge coefficient and obtained values close to validating the proposed expected analytically.
