Essay on Fluid Mechanics Lab

E. What would happen if you dropped the object into the beaker while using the Archimedes’ Principle method instead of submerging the object?

I hereby declare that, except where I have made clear and full reference to the work of others, this submission, and all the material (e.g. text, pictures, diagrams) contained in it, is my own work, has not previously been submitted for assessment, and I have not knowingly allowed it to be copied by another student. In the case of group projects, the contribution of group members has been appropriately quantified.

As a result of the experiment and computation of data, the aerofoil was found to have a critical Mach number of M=0.732. Below this freestream Mach number the Prandtl-Glauert law predicted results very

Plagiarism occurs when a student attempts to pass off as their own work, the work of another, without any acknowledgement as to its authorship or source.

Let the mass of the fired bullet be Mb. It is fired at an initial velocity of v. The momentum

Assuming no viscous forces present an inviscid model has been used for the calculations. Also from the equation of the Reynolds number Re=ρvl/μ due to Re being really big rearranging and assuming v and l to be constant the viscous force μ =ρvl/Re becomes negligible.

1. The force of the window on the bug because the bug is just flying, but the force of the window at a given speed is much greater creating the force to splatter the bug.

(Melvin, Mangonel - “Physics of Catapults”) The speed and distance of the projectile depended on how much force the catapult applied to the projectile, and the momentum depended on the mass and the velocity of the projectile (dead diseased cow, or flaming

Both the orifice and the Venturi meters produce a restriction in the flow and measure the pressure drop across the meter. The velocity of a fluid is expected to increase as the fluid flows from an open area, to a more constricted area. Assuming incompressible flow, a negligible height change, and steady state, Bernoulli’s equation can be simplified to show the correlation between the volumetric flow rate and the pressure drop. The equation for both meters is as follows:

6. The outflow rate is measured by using a measuring cylinder. It is measured 3 times and averaged for a more accurate result. The results are shown in Table 2.

a) Transfer pipette was obtained. The pipette was cleaned because distilled water does not drain uniformly. A cleaning solution or detergent was used to clean the pipette.

-The Reynolds number of this experiment was then calculated using equation (4) where c is the length of the aerofoil chord and is the dynamic viscosity of air.

If you are part of the group, you will receive one grade for this assignment. However, I reserve the right to report different grades for group members if I determine a substantial imbalance in the level of effort put forth. Each member of the group will also be required to evaluate the other group members using an Evaluation Form that I will provide to you.

Considering a viscous liquid that is being pumped through a smooth pipe with the parameters:
