Complete 8 pages APA formatted article: The Bernoullis Experiment. The experiment demonstrates succinctly that the venture is a means for establishing flow measurement and, from which, the discharge coefficient can be derived. From the results, it is right to say that the pressure difference increases as the level of water in the manometer tubes increases.
.Chapter 1: Introduction
Bernoulli’s principle, named after its founder, Daniel Bernoulli, asserts that “as the speed of a moving fluid (liquid or gas) increases, the pressure within the fluid decreases. In which case, the use of Bernoulli’s equation guides the significant concepts in the definition above. The equation makes use of the relation between pressure, velocity, and elevation (height). This is different from the continuity equation, which only applies a connection between n speed of the fluid and the cross-sectional area measured for a pipe in which the fluid moves. It is worth noting that there are certain restrictive conditions to which the principle can hold. This includes, the fluid used must be frictionless at a constant density, in which case, steady flow is a must. .

Since frictional effects are most significant when very close to the boundary layers, the use of Bernoulli’s approximation is feasible outside the boundary layers, in which case, the flow outside is guided by the combination of two forces, pressure and gravity. The concept conveyed can be explored based on the law of conservation of energy. As a result, the fluid broader section of a pipe to a constriction triggers a more significant distance movement of the contraction’s corresponding volume, thereby increasing speed. The aspects explained therein, constituting work done in both broader and narrower sections, can be summarized into the pressure and volume product. The greater rate evident leads to the higher kinetic energy of the given volume in the thinner pipe. Going by the law of energy conservation, the observed increase of kinetic energy is thereby balanced by a decrease in the pressure-volume product, as shown in Bernoulli’s equation below (Durgaiah 2002, 50).
Kinetic energy + potential energy + flow energy = constant
The centerline, while considering the assumptions that the fluid used must be frictionless at a constant density. in which case, steady flow is a must:
From the above Bernoulli’s equation, the total head (h) is obtained from summing up the pressure head (h), velocity head (HV), and elevation head (z), respectively, as depicted on the left-hand side of the equation. .
