un-notched specimen is comparable to that of a notched specimen. Similitude suggests that the component fatigue life of the two objects will also be similar. One example that we can give here is the ‘PIPE FRICTION APPARATUS’. Pipe friction apparatus has been designed for students to measure pipe friction losses for laminar and turbulent

`A 20cm diameter pipe of length 100m with z = 60m with f = 0.02 and loss of head due to entrance coefficient k = 0.5. What is the flow rate? Solution: Find the width in m of the channel at the back of a suppressed weir using the following data: H = 28.5cm; d = 2.485m; Q = 0.84 cu.m/sec. Consider the velocity of approach and use the Francis formula. Solution: Water flows in a 2m. wide rectangular flume at the rate of 2.75 cu.m./sec

bottom of the hole by a drill string consisting of hollow steel pipes of circular section screwed together. The cuttings produced by the bit are transported up to the surface by a drilling fluid‚ usually a liquid (mud or water)‚ or else a gas or foam‚ circulated in the pipes down to the bit and thence to the surface. The rotation is transmitted to the bit from the surface by a device called the rotary table (or by a particular drive head)‚ or by downhole motors located directly above the bit. After

LABORATORY Fluid Friction Measurements 1. Objective: Ø To determine the head loss. Ø To determine the head loss associated with flow of water through standard fittings used in plumbing installations. Ø To determine the relationship between friction coefficient and Reynolds’ number for flow of water through a pipe having a roughened bore. Ø To determine the water velocity by using flow measurement devices. 2. Equipment: The test pipes and fittings are mounted on a tubular frame carried castors. Water

project?” There are many excellent trenchless construction methods to consider in addition to microtunneling: auger boring‚ pipe jacking‚ guided auger boring‚ pipe ramming‚ guided pipe ramming‚ horizontal directional drilling and conventional tunneling. Depending on the project length‚ diameter‚ ground conditions‚ groundwater conditions‚ access restrictions‚ allowable pipe material‚ permits‚ available right of way and available shaft locations‚ microtunneling may not be the preferred construction

improved by lining the canal and by proper leveling of the field. Sub-surface method The method is suitable for specific types of soils. Evaporation and other losses are reduced considerably since water is applied below the surface through porous pipes. Sprinkler method Water is applied in the form of rain. Water is conveyed through pipes and sprayed though sprinklers. This method is most suited for steep sloppy and sandy soils. Drip irrigation Drip irrigation is adopted in water scarce areas

behaviour of water through a pipe of variable section. Firstly‚ we will investigate the interchange of pressure and kinetic energy at each diameter change. Secondly‚ we will study the application of this interchange to the flow metering devices. Lastly‚ energy losses due to friction and pressure effects are estimated. Experimental Apparatus [pic] Pre-lab Question Pressure varies along the pipe. Explain why this is the case. The pressure will vary along the pipe because of several factors
