Fluid dynamics

The purpose of this lab is to evaluate the relationship between kinetic friction coefficient and static coefficient as well as measure the coefficients of the two friction. Friction is the force that resists relative tangential movement. Its direction is opposite to the relative velocity. Kinetic friction and static friction are two types of friction. Static Friction happens when the two surface in contact remains relatively stationary to each other. It reaches its maximum value before the…

Coulter Counter Method. Schematic Diagram Diagram 1: The basic setup of coulter counter method. Test tube containing conducting fluid placed in the beaker containing same conducting fluid. Orifice in the test tube connect the circuit. Electrodes are placed in beaker and test tube and voltage is applied. Vacuum is applied in the test tube to allow fluid movement from beaker to test tube. Counting circuit will calculate the amount of particle and pulse height analyser will measure the particle…

COMPARATIVE STUDY ON FRICTION WELDED AND ELECTRON BEAM WELDED JOINTS MADE BY 20VNiMoCr120 STEEL Gabriela IANCULESCU*, Lucia Violeta MELNIC, Marian Andrei GURĂU Ovidius University of Constanta Abstract: In the paper there are presented experimental results concerning mechanical characteristics of friction-welded joints in comparison with electron beam welded joints, made by 20VNiMoCr120 heat-resistant steel, which are part of some elements working at high pressure and temperature. The paper…

1- Summary This study is based on the analysis of pressure distribution around a NACA 23015 airfoil section with a flap of length equal to the 30% of the cord at different angles of incidence and flap settings. The experiment was performed in a non –return wind tunnel at a Reynolds number of 4.4×〖10〗^5 and at a Mach number of 0.073. It is of note that increasing incidence will increase lift produced until the critical angle of attack, where the airfoil stalls; moreover, deploying a flap will…

The blast wave generating device developed for this project consists of two sections that are equivalent in cross sectional area to the expansion section channel of the shock tube; the front section has internal damper blades that rotate from a vertical position to a horizontal position, and the rear section is equipped with internal flow straighteners. The device is to be placed in series between the expansion section and the expansion section channel, and bolted together with the flanges of…

The bouncy ball is way bouncy then the tennis ball, because the bouncy ball is made of the rubber and when it hits the ground it gets compressed, or squished and because it is very elastic, it returns to its original shape very quickly. That's the only reason why the bouncy ball is way bouncier than the tennis ball. Bouncy ball was made by the one and only norman stingley who worked at the california chemist. He used to just experiment stuff with rubber on his spare time. By doing all the…

should be transmitted without being obstructed. After familiarized with the lab instruments, the LabVIEW program for AE 460 should be started. Then, the current ambient pressure, the current ambient temperature, and a calibration coefficient for dynamic pressure correction, q correction factor, should be inputted into the program under the…

Therefore, if the pressure filter is semi blocked (not fully blocked), the flow rate decrease at the orifice makes the pressure at pump will be increased and suddenly, the pressure decreases after pass the orifice. Schaschke (2005) stated that a drop in fluid pressure because the increase in the cross-section causes a reduction in velocity and an increase in pressure. The kinetic energy is decreased and the potential energy which is in a form of pressure will increase simultaneously then, they…

properties of basic fluid flow we which know today as “Bernoulli’s Principle” (The Doc). Though many are informed on the basis of Bernoulli’s Principle, how many of us can say we are familiar with the math behind this theory? To refresh your memory, Bernoulli’s Principle states that the pressure of a fluid decreases in areas where the flow velocity increases. Imagine…
