Fluid friction in pipes is particularly important to process design engineers pump energy consumption comprises a significant portion of operating costs, and a substantial amount of resources is devoted to purchasing piping and equipment that minimize fluid friction. Major losses the major head loss in pipe flows is given by equation 3 (3) where l and d are the length and diameter of the pipe, respectively, v is the average fluid velocity through the pipe and f is the friction factor for the section of the pipe. The friction factor is a function of the reynolds number re and the non-dimensional surface roughness / d , and is determined experimentally the plot of f vs re is usually referred to as. This is because of the friction losses in the real fluid ideal fluid does not have friction losses from the experiment it can be conclude that with decrease in area of flow there is an increase in velocity and decrease in the flow pressure of the fluid. Fluid experiment 3: fluid flow friction and fitting loss objective to determine the pressure or head loss in different diameters pipes, joints and valves theory pipe flows belong to a broader class of flows, called internal flows, where the fluid is completely bounded by solid surfaces.
Friction losses in pipes live experiment 2015 skip navigation sign in search sign in to report inappropriate content amazing friction welding. Fluid mechanics laboratory 2 report robby joseph 14103508 10 introduction this experiment was undertaken for the study of flow in pipes and the factors that affect it in both laminar and turbulent regimes. Friction losses during the flow of fluid in the pipe are due to the friction forces present between the fluid particles and between the pipe wall and fluid particles this friction force uses some of the force present in the flowing fluid and due to this difference in the height of manometers (present on the same pipe at some distance) occurs. Experiment a - fluid friction in a smooth bore pipe objective to determine the relationship between head loss due to fluid friction and velocity for flow of water through smooth bore pipes and to confirm the head loss friction factor f.
A friction lab report is a lab report that describes the results of an experiment involving some aspect of friction, or the resistance of motion as two items move against one another. Fluid mechanics matthew p juniper 51definition of the friction coefficient the friction coefﬁcient, cf, is the non-dimensional wall shear stress, ˝wthe wall shear stress is a force per unit area and has dimensions nm 2. When a fluid flows in a closed conduit pipe, its energy loss can be demonstrated in this experiment frictional head losses of the fluid flow in a pipe may be calculated using experimental and theoretical coefficients used in the three empirical formulas listed in subsequent theory section. A continuous pipe flow rig is used in this lab experiment, as sketched in figure 2 the flow is pumped from the water tank as shown, and makes a 180o turn so that the flow exits back into the water tank.
Fluid flow is an important part of many processes, including transporting materials from one point to another, mixing of materials, and chemical reactions in this experiment, you will. Belt friction experiment lab report pdf friction experiment lab report belt friction full report belt (mechanical) friction, belt friction is for experiment that use in the lab and the report is ready for all its contains objective, discussion and conclusion. 90 9 friction loss along a pipe introduction in hydraulic engineering practice, it is frequently necessary to estimate the head loss incurred by a fluid as it flows along a pipeline. Pipe friction is one of the classic laboratory experiments and has always found a place in the practical teaching of fluid mechanics with this unit, friction head losses in straight pipes of very different sizes can be investigated over a range of reynolds' numbers from 103 to nearly 105. Fluid mechanics lab experiment (12): major losses (fluid friction in a smooth bore pipe) mechanics lab experiment (12): major losses 2 instructors : dr.
In this experiment you will investigate the frictional forces inherent in z white, f m 2003, fluid mechanics, 5th edition, friction factor, reynolds number. Fluid mechanics 3-aerofoil lab report introduction this report aims to investigate the effect the angle of attack of an aerofoil has on the air flow around it this was done by recording the lift and drag forces the aerofoil experienced when positioned at different angles of attack. Fluid friction apparatus h408 - experiment a floor standing apparatus to allow students to investigate the phenomena of laminar, transitional and turbulent flows in pipe systems.
The experiment was undertaken to measure the head lost in the pipe due to shear stress between the fluid and the wall of the pipe different flow rates were introduced along with a different diameters and roughness of the pipes therefore we measured the friction factor of the pipes using our. Determine the slope of the straight line o confirm that the head loss can be predicted using the pipe friction equation provided the velocity of the fluid and the pipe dimensions are known o confirm that the graph is a straight line for the zone of laminar flow. Experiment no 4 | group 3 | may 24,2016 3 relative roughness on the friction factor of the fluid flow methodology the equipment used in the experiment was the fluid- flow set-up and the materials used were steel tape, stopwatch and thermometer. The force of friction we will be completing a formal lab report on the force of friction fluid friction is usually less than sliding friction.
Fluid friction - friction that happens when an object moves through a liquid or gas sliding friction - friction that occurs when two surfaces slide over each other rolling friction - friction that is produced when a circular object rolls over another surface. Introduction in this experiment, we tried to determine the relationship between head loss due to fluid friction and velocity for flow of water through smooth bore pipes and to confirm the head loss predicted by a pipe friction equation.
