Friction loss experiment lab report

I am looking for someone to help me with my lab report for my Mechanical engineering class. I will provide with all the information needed for the lab including the lab report formFluid Friction - The H408 Fluid Friction Apparatus UTD Mechanical Engineering Fluids Lab (MECH 3115) Dr. Hui Ouyang Outline • • • • • • Fluid friction Experimental instruments/apparatus Experimental procedure Data collection Data analysis Results and discussion Introduction to fluid friction • When the fluid is viscid, ‘sticky’, if there is velocity difference within water ‘particles’ or between water particle and other surface (wall), friction will occur (shear force). • Friction will cause energy dissipated into the environment instead of keeping the energy within the fluid. • The energy ‘lost’ to the environment is quantified by friction loss. • Friction factor, f and loss coefficient ,k can give us a general ideal of the friction loss in current internal pipe system. • Further, by understanding friction loss, optimized pipe system can be designed to meet human needs. • There is al way s frictional loss (head loss) in internal flow of a viscous fluid. Introduction to fluid friction • This loss can be intensified by roughening the pipe, changing direction in the flow sharply, or introducing different geometries into the path. • Friction factor, f - Lewis Moody created an empirical chart that allowed us to calculate the expected loss as a function of roughness/diameter and Reynolds number for straight pipe only (major loss). • Loss coefficients must be handled as localized losses (minor loss). Experiment apparatus Cautions: • At least one exit valve needs to be open before opening the inlet valve. • Only the channel for the current interest needs to be open, every other exit valve remain closed. • When switch to a different channel, open the designated exit valve first, then close the previous one. • Watch out for water spill from the piezometer. Experimental Procedure 1. Start the flow bench. 2. Adjust the valve on the flow bench to your desired flowrate, and make sure at least one outlet valve is open. 3. Open the flow through the section of pipe you wish to measure head loss through (ensure all other pipes are closed) 4. Record the readings in piezometer, ∆h. 5. Repeat 2-4 for different sections.at and calculation background. I have attached a general information regarding the report and I will provide you with all the data and further information through the chat.
