In this experiment, the head loss water is the variable constant whereby flow rate of water is the responding variable. As noticed, the flow rate of the water increases with respect to the height of water from 1. If required, further control of levels can be achieved by use of the hand-pump to raise the manometer air pressure. It is assumed that the dynamic viscosity μ is 1. For turbulent flow, the pressure drop is dependent on the roughness of the surface, while in laminar flow, the roughness effects of the wall are negligible. Overview A pump can serve to move liquid, as in a cross country pipeline, to lift liquid as from a well or to the top of a tall building; or to put fluid under pressure as in.
Students use a Venturi meter and an orifice plate meter and compare the losses of each. The head is measured in mm. Now refill the stainless steel containers as in step 2. To interchange test specimens, turn off the flow pump, disconnect the blue tubing quick connects from the static pressure taps. It essentially depends on the friction coefficient and the relative roughness. This is why if you roll a ball on the ground it eventually stops. Velocity in the piping network only varies in reducer and enlarger.
Prepare a table of all the experimental results for each pipe section. The relation is therefore most commonly known as the Darcy-Weisbach formula. The discharge of the water is controlled by a controlling valve. Lab-09- The Physics of Inclines. The diameters are listed in Table 1 below. They are presented in terms of the linear head loss versus the Reynolds number. Finally, when finished with the data acquisition, turn off the flow pump.
Details of the friction records for slow events show that slip begins. Hoffman Clamp white Measuring Cylinder next to outlet pipe Join the test rig inlet pipe to the hydraulic bench flow connector with the pump turned off. As shown in Table 3. In Head Loss in Piping Systems. The concentration of particles along a concentration gradient is called diffusion. Note the reading of manometer and note the temperature of water 4.
All levels tubes are connected to each other at the top end and have a joint vent valve. This view was further elaborated by Belidor representation. Presentation of the Data 10 1. Investigation and laboratory evaluation of the phenomena behind the dynamic. Fluid Mechanics Laboratory 2 Report Robby Joseph 14103508 1. Aim This lab could be used in industry when dealing with a pipe line containing any type of liquid to calculate the Reynolds number and friction factor. Can Snapchat Show It's More Than a Lab For Unconventional Ads? Hypothesis If static friction is the largest force, then either.
He produced the necessary curves for the Colebrook transition zone. Using Excel or Notepad, make a printout of the data file for each case, making sure each table is properly titled and labeled. Flow rate measuring devices 4. Air bubbles in any of the pressure lines will lead to gross errors in your data. Quick connects are used so that various test specimens, such as long straight sections of pipe, or sections of pipe with various minor loss devices, can be easily interchanged. Several other investigators provided the literature with diverse diagrams.
This permits the levels in the limbs to be adjusted for measurement of small differential pressures at various static pressures. Add to My Quote The Friction Loss in a Pipe apparatus allows students to study the change in the laws of resistance for laminar to turbulent flow and find the critical Reynolds number. Put data from all the pipes on the same plot, being sure to identify the pipes with a legend. Table 1: List of pipe fittings. Every error has its own solution to improve the results obtained from the experiment.
Calibration of the Electronic Pressure Transducer associated with Head Loss To simplify the task of data collection, the major head loss hmajor through the test specimen is measured electronically by the computer data acquisition system. The F1-18 Pipe Friction Apparatus. If required these values may be checked as part of the experimental procedure and replaced with your own measurements. Repeat for all the pipe specimens. Manometer m h 2 Measured Head at outlet to test section of the pipe. P net 9251 2511 9251 2466 a ic 134 34 134 69 1830 1772.
Fluid dynamics, Liquid, Mass 533 Words 8 Pages An Experiment of Adaptation Introduction: Throughout history of time, organisms change in relation to their environment, consequently, adaptation is an essential property of life. Aerodynamics, Continuum mechanics, Fluid 519 Words 3 Pages 1. This tends to loss of energy head in the fluid flow. In the case of smooth wall of pipe, there is less effect on the frictional resistance. The Digital Hydraulic Bench H1F, available separately supplies the circuit with a controlled flow of water.
On top of that, referring to Graph 2. Using the three valves in combination, it should be possible to achieve fine adjustment of the flow if required. In addition to the energy lost due to frictional forces, the flow also loses energy or pressure as it goes through fittings, such as valves, elbows, contractions and expansions. Therefore, this graph inhibits the same properties as Graph 2. In the average person water constitutes 60% to the total body weight. Ball valve, Fluid dynamics, Gate valve 1962 Words 6 Pages Daphnia Experiment Report 1. The transitional regime between laminar and turbulent flow will also be studied.
