Text of Expt. 1 - Bernoulli (Prelaboratory)

A Study of Bernoullis TheoremPROBLEM A1Costales, ElijahMag-isa, Von JustinMiranda, Kenneth PauloTamayo, Benedict ChristianWho is Bernoulli?Daniel Bernoulliestablished the fundamental relationshipbetween the properties of basic importance in fluid flow, particularly pressure, density, and velocity in his written work, Hydrodynamica(1738).[1]What is Bernoullis Theorem?The total mechanical energy of the flowing fluid fluid pressure, the gravitational potential energy of elevation, and the kinetic energy of fluid motion, remains constant. Bernoulli's theorem is the principle of energy conservation for ideal fluids in steady, or streamline, flow.The ExperimentAt steady state flow, The total mechanical energy of the flowing fluidremains constant. + 12

2+ = 0The Bernoullis theorem demonstration apparatus was used to analyze the flow of fluid along a vessel.The ObjectivesDetermine the validity of the Bernoullis Theorem on the flow of water in a tapering circular duct by comparing the theoretical total head and the observed total head at a given flow rate.Determine the range of validity of the Bernoullis Theorem using water flowing at different flow ratesThe MaterialsThe MaterialsThe MaterialsProcedureRemove air bubblesTurn the valve to Fully OpenLet water flow until air bubbles are removed.ProcedureKnow maximum and minimum heads that they can reachProcedureAssume flow rate by adjusting inlet and/or valve.Note: DO NOT change or move the inlet and valve YET. Just Let It Flow Let It Flow..ProcedureReading the ManometerInsert the probe to fullRecord the level in each tubes. Note: Pressure Head/Probe Manometer/TheoreticalProcedureReading the ManometerMove the probe end to the tapered portion.Record the level in each tubes. Note:Total Head/Manometer Level/ExperimentalProcedureProcedureCheck the type of flow.*Type of flow in points 1-6 should be the same.Laminar: water might not go out the exit streamTransitional : can have 1 point that is not transitional.Turbulent: The flow shouldnt be obviously turbulent
