Fluid mechanics Lab Report
The transitional regime between laminar and turbulent flow will also be studied. The scale is divided into two zones corresponding to the volume above and below the step in the tank. Slotted masses 200g with hanger 4. This type of lost depends on the shear stress due to the walls of the pipe and the fluid. At intermediate velocities, transitional flow is observed where the filament is found to be fluctuated in the water. Every error has its own solution to improve the results obtained from the experiment.
All the test pipes and fixed interconnecting pipes are fabricated in stainless steel. The water manometer includes an air valve and hand-pump. A wide range of measurements, demonstrations and training exercises are possible with the equipment: confirming the relationship between head loss due to fluid friction and velocity for flow of water determining the head loss associated with flow through a variety of standard pipe fittings determining the relationship between pipe friction coefficients and Reynolds' number for flow through a pipe with roughened bore demonstrating the application of differential head devices in the measurement of flow rate and velocity providing practical training of pressure measurement techniques enhancing understanding of the hydraulic principles involved through the use of complementary computer software. The motion has now becomes turbulent. A row of control valves mounted above the flow table is used to adjust the flow through each individual source. Order Codes: H12-2: Liquid manometer H12-8: Portable pressure meter Also available for use with manual data aquisition instruments is a software package, which performs all the neccessary calculations from readings entered manually.
. Add water if necessary to the water tank so that the flow pump is fully submerged. Conclusions The objectives have been fulfilled and proven on the experiment shown above. It is proven that the higher velocity along the smooth bore pipe, the higher is the head loss of water. Add water to or drain water from, using the blue thumb wheel pincher on the drain lines one of the calibration containers if necessary until the water in both containers is at the same level approximately 68 inches on the manometer scale, which has an arbitrary datum plane. The data should automatically be stored onto the file you created previously.
Major loss is generally takes place in long pipe due to friction. Slowly return the low pressure calibration container to the upper shelf. A suitable stilling arrangement diffuses the water flow prior to entry into the channel, ensuring smooth, uniform flow. When test conditions have stabilised, the dump valve is lowered, retaining the water in the tank. Similarly, the sinks and sources may be used in combination with the flow of water between the plates to simulate a variety of flow situations. On top of that, it is sure that when the height of water increases will affect the height of the mercury as well but based on results obtained, the height of water is higher than the height of mercury. Place both stainless steel calibration containers on the top shelf of the calibration stand, side by side.
Green Mechanic: Laminar and Turbulent Pipe Flow Lab Report
The region where the pressure is high the loss in the pressure drop will be also comparatively high. A diffuser in the inlet tank and an adjustable weir plate in the discharge tank help to promote a uniform flow of water. Prepare a plot of friction factor f versus Reynolds number for the pipes tested here. Aerodynamics, Fluid, Fluid dynamics 992 Words 4 Pages Pipe Friction Summary The purpose of this lab is to find the friction factor and Reynolds number for laminar and turbulent flow and also for values in the critical zone. In Head Loss in Piping Systems.
Circle the correct way, and give a brief explanation for your choice: L Test specimen High pressure tap Low pressure tap Test specimen High pressure tap Low pressure tap L 6 2. Then disconnect the pipe quick connect at the upstream end of the pipe and remove the pipe test specimen. Various schemes for pre-paid and post paid customers Conclusion and Recommendation:. Jets can travel long distances without dissipating, Jet profile refers to the trajectory followed by jet during the experiment. In this experimental result the major part of the head loss is taking place due to minor loss factors.
Now refill the stainless steel containers as in step 2. V1 is opened gradually and the piping is allowed to fill with water until all air has been expelled from the system. Negative intrapersonal communication is a powerful barrier that can increase the severity of academic and personal consequences for… 1705 Words 7 Pages Introduction Head loss in a pipe flow is mainly due to friction in pipes and again friction is due to the roughness of pipes. There are existences of errors in every experiment and therefore errors were arisen in this experiment as well. In this experiment, we controlled the height of water and determine the flow rate of water along the pipe whereby a more precise and contented results obtained.
The pressurised water manometer incorporates a Schrader valve which is connected to the top manifold. Friction is the resistance to motion between two objects in contact with each other. These major head losses were normally due to wall friction in the pipe and viscous. The unit is designed for use with the Armfield F1-10 Hydraulics bench. Note down the manometer reading at different locations and repeat the procedure for two more volume flow rates.
