Chapter 7 flow through pipes 71 friction losses of head in pipes 72 secondary losses of head in pipes 73 flow through pipe systems 71 friction losses of head in pipes. Head losses due to singularities or accessories are commonly termed minor head losses. Friction losses in straight pipe reynolds number fluid. Now that you know already how to calculate friction factor, is time to calculate friction loss due to flow in pipes. The pressure drop for the minor losses can be found by using equation 1 cengel, cimbala, 2014. The value for hl is obtained by diving the pressure drops across the sections of pipe by the product of the density kgm 3 of the fluid and gravity ms 2. Factors that affect head loss are flow rate, inside diameter of the pipe. The pressure losses across the two sections of pipe head loss, hl is used to find the darcy friction factor f for the sections of pipe. Ramith bulumulle 24698512 don gayanga millevithanatchy 24829781 zhi ying lim 23725540 26102014 abstract the principle examined in this experiment was how the frictional flow of a fluid in a pipe relates to the relationship with the fluids reynolds number.
This this is due to the fact that for pipes of important length, their value can be neglected comparatively. Two types of energy loss predominate in fluid flow through a pipe network. Doc mec2404 frictional flow in pipe lab report done by. Head losses in pipes fluid flow lab report docsity. Applied fluid mechanics lab manual by habib ahmari and shah md imran. Discussion from this experiment will obtain data that will tell us whether the water flow is turbulent or laminar. In this experiment for sudden contraction is diameter 1 is 25 mm and. Example lab report losses civl2310 fluid mechanics uon. The specific hydraulic model that we are concerned with for this experiment is the energy.
There are many types of losses of head for flowing liquids such as friction, inlet and outlet losses. Friction loss in pipes applied fluid dynamics class 032. By know the major head losses due to pipe diameter over a length o f pipe and the minor head. Example lab report losses civl2310 fluid mechanics. Introduction if you want to move something, there will be resistance. Friction loss along a pipe introduction in hydraulic. The term minor losses, used in many textbooks for head loss across fittings. Minor secondary head losses occur at any location in a pipe system where streamlines are not straight, such as at pipe junctions, bends, valves, contractions, expansions, and reservoir inlets and outlets. Friction losses in pipes live experiment 2015 youtube.
