Fluid FlowBERNOULLI’S EQUATIONBERNOULLI’S EQUATIONBernoulli’s equation is a special case of the general energy equationthat is probably the most widely-used tool for solving fluid flowproblems. It provides an easy way to relate the elevation head,velocity head, and pressure head of a fluid. It is possible to modifyBernoulli’s equation in a manner that accounts for head losses andpump work.EO 1.14 DESCRIBE the relationship between Bernoulli’sequation and the First Law of Thermodynamics.EO 1.15 DEFINE the term head with respect to its use in fluidflow.EO 1.16 EXPLAIN the energy conversions that take place in afluid system between the velocity, elevation, andpressure heads as flow continues through a pipingsystem.EO 1.17 Given the initial and final conditions of the system,CALCULATE the unknown fluid properties using thesimplified Bernoulli equation.EO 1.18 DESCRIBE the restrictions applied to Bernoulli’sequation when presented in its simplest form.EO 1.19 EXPLAIN how to extend the Bernoulli equation tomore general applications.EO 1.20 RELATE Bernoulli’s principle to the operation of aventuri.GeneralEnergyEquationThe conservation of energy principle states that energy can be neither created nor destroyed.This is equivalent to the First Law of Thermodynamics, which was used to develop the generalenergy equation in the module on thermodynamics. Equation 3-8 is a statement of the generalenergy equation for an open system.Q + (U + PE + KE + PV)_{in} =W + (U + PE + KE + PV)_{out} + (U + PE + KE + PV)_{stored}(3-8)Rev. 0 Page 21 HT-03
