Introduction This laboratory experiment will attempt to show the importance of the Bernoulli’s theorem and the way it can be used to solve a wide range of fluid mechanics problems. This theorem was developed by Daniel Bernoulli, a Swiss mathematician that is particularly remembered because of his remarkable contributions to the study of fluid mechanics. Bernoulli’s theorem comes from the law of conservation of energy and states that along a streamline for an incompressible, frictionless and steady fluid flow the energy at the beginning of the streamline must be equal to the energy at the end.

Unformatted text preview: this lab as the assumed frictionless flow has the same elevation in all sections the total head at each section must remain constant in order to prove the theorem. Summary of Procedure: Place the apparatus on the hydraulics bench and level it. Flood the manometer bank with water in order to remove all the air bubbles. Adjust the water levels in the manometer by adjusting the control valve until the difference between the highest and the lowest levels achieves the largest convenient differential value. Insert the total head probe to the end of the duct until the end of it lies underneath the first pressure tap. Now record the total head from the manometer in the bank in the six pressure taps. Measure the flowrate by determining the time required by the system to fill a volume of 3 liters of water. Repeat this measurement two times to increase accuracy. Now repeat the whole procedure for a different flowrate....
