Wind tunnel A wind tunnel is a tool used in aerodynamic research to study the effects of air moving past solid objects. A wind tunnel consists of a closed tubular passage with the object under test mounted in the middle. A powerful fan system moves air past the object; the fan must have straightening vanes to smooth the airflow. The test object is instrumented with a sensitive balance to measure the forces generated by airflow; or, the airflow may have smoke or other substances injected to make

Experiment #3 Venturi Meter Fluid Mechanics Lab Abstract Flow rate is a common measurement which often needs to be performed. A venturi meter allows the flow rate in a pipe to be determined from a pressure differential. A venturi narrows the diameter of the pipe for a short duration, converting pressure head to velocity head. Through this pressure differential, Bernoulli’s equation, and the known dimensions of the venturi, the flow rate of the incompressible fluid can be determined. I

Impact Of a Water Jet • Introduction: Over the years, engineers have found many ways to utilize the force that can be imparted by a jet of fluid on a surface diverting the flow. For example, the pelt on wheel has been used to make flour. Further more, the impulse turbine is still used in the first and sometimes in the second stages of steam turbine. Firemen make use of the kinetic energy stored in a jet to deliver water above the level in the nozzle to extinguish

the different sizes in air stones. From the ANOVA illustrated in Figure 1, the sources X1, X2, X3, X4 are oxygen flow rate, stone size, stirrer speed, and groups respectively. It is seen that the largest variance occurs at the stirrer speed parameter, with a F value of 24.71 as compared to oxygen flow rate at 1.82, stone size at 1.98 and groups at 0.15. This shows that the stirrer speed plays the most significant role in the variation between the sets of data. One of the reasons that might have caused

thereby calculating the values α and β in the KLa correlation: KLa = K[Pg/V]α (Vs)β KLa is the volumetric liquid phase mass transfer coefficient indicative of the mass transfer of oxygen dissolved in the liquid to the cell. It is calculated using the dynamic method which is usually used for vessels which are less than 1m in height because there is nitrogen gas hold-up in the vessel when air is reintroduced and the measurement of concentration of oxygen in the liquid does not reflect the kinetics of simple

INTRODUCTION An exactly analysis of the landing gear, as designed on modern aircraft’s, is necessary to understand the construction and systems of the landing gear of the Airbus A320. Operation of the landing gear is made possible through extension/retraction, steering, braking and damping systems. In order to maintain the safety of the aircraft, the design of the landing is satisfied to the legislation of the European Aviation Safety Agency . With the knowledge of the landing gear construction

Subject: Converging-diverging nozzle experiment In this experiment, we used manometers to measure the pressures in the nozzle relative to atmospheric pressure. A water manometer is connected to the inlet pressure tap (P0-P1) and also connected to the throat (P0-P2) and downstream (P0-P3) pressure taps as well. To start this lab we adjusted the flow rate to increase (P0-P3) in equal steps of 2.5 inches of water until the nozzle is choked, which means there is no further increases in (P0-P2) and
