Fluid Report 2 In the derivation of Bernoulli’s equation‚ the assumption of the inviscid and incompressible flow is used. However in the real case‚ the viscosity cannot be neglect and the density of the flow is not always constant. Thus Bernoulli’s equation is not always correct. For the lab‚ it is reasonable to assume the flow is inviscid and incompressible. Firstly‚ the pitot was placed at the center of the flow. The skin friction (effect of viscosity) is inversely proportional to distance

Lecture No. 5 CLASSIFICATION OF FLUID FLOW AND THE CONTINUITY EQUATION 5.1 Classification of Fluid Flow Uniform flow If the velocity of the fluid is the same in magnitude and direction at every point in the fluid the flow is said to be uniform. Non-uniform flow A non-uniform flow is one where the velocities at different points at a given instant are not the same. Every fluid that flows near a solid boundary will be non-uniform because the fluid at the boundary takes the velocity of the

Although a significant distinction exists between liquids and gases‚ both types of fluids obey the same laws of motion. In most cases of interest‚ a fluid can be regarded as continuum‚ i

Experiment 1 Fluid Flow In A Smooth Pipe Abstract In this experiment‚ three variable flow meters are used to alter the flowrate. Changes in pressure drop due to the change in flowrate are then observed from the three pressure gauges that can measure pressure at different range and recorded. The shift from laminar flow to turbulent flow is seen from the results recorded‚ but it is observed more clearly from the water-soluble dye experiment that was carried out by the demonstrator. Laminar flow turns to
