Pipe Friction Summary The purpose of this lab is to find the friction factor and Reynolds number for laminar and turbulent flow and also for values in the critical zone. Results were taken recorded and used to calculate the friction factor and Reynolds number. They were then compared with the Moody diagram. 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. It would also help in pipe

EXPERIMENT 1 – HEAD LOSSES IN PIPES Introduction: In this experiment‚ the aim is to find the losses of water flow in a pipe system.There are two types of losses. First the major losses which is caused by the the frictional effect of pipe. Second one is the minor losses which is caused by the turning points(corners) of pipes. Apparatus: • • • • • • 90° mitter bend 90° elbow bend 90° large radius bend Sudden enlargement in pipe diameter Sudden contraction in pipe diameter A pump to supply water

Abstract The objective of this lab was to determine the relationship (if any)‚ between the pressure and volume of a gas given the temperature and # of molecules remained constant. Using the Boyle’s law apparatus‚ and textbooks to demonstrate pressure it was concluded that there was a relationship between pressure and volume. However‚ the relationship was not a direct relationship‚ and it was determined that the pressure and volume of a gas are inversely proportioned. Thus‚proving Boyle’s theory

Bernoulli’s theorem when appliedto the steady flow of water in tapered duct and to measure the flow rates and both static andtotal pressure heads in a rigid convergent/divergent tube of known geometry for a range of steady flow rates. The Bernoulli’s theorem ( Bernoulli’s t heorem‚ 2011) relates the pressure‚velocity‚ and elevation in a moving fluid (liquid or gas)‚ the compressibility and viscosity(internal friction)of which are negligible and the flow of which is steady‚ or laminar. In order to

Laboratory Apparatus Beakers are useful as a reaction container or to hold liquid or solid samples. They are also used to catch liquids from titrations and filtrates from filtering operations. Bunsen burners are sources of heat. Burets are for addition of a precise volume of liquid. The volume of liquid added can be determined to the nearest 0.01 mL with practice. Clay triangles are placed on a ring attached to a ring stand as a support for a funnel‚ crucible‚ or evaporating dish.

THE EARLY HISTORY OF PVC PIPE By Robert Walker‚ P.E. Uni-Bell PVC Pipe Association (Published in Summer 1990 Edition of the Uni-Bell PVC Pipe News) “Many of you have expressed a curiosity about the historical development of PVC pipe. In response to your requests‚ we provide you with this brief early history of PVC pipe and fittings. PVC was discovered as early as 1835‚ but the first definite report of the polymerization of vinyl chloride did not come until about 35 years later. At that

CHE2161/MEC2404 Frictional Flow in Pipes Experiment : Friday 8.30-11.30am Conducted In : Fluid Mechanics Lab Abstract The main aim of this experiment was to show how the friction factor varies with Reynolds number by manipulating the flow rate of the fluid in a pipe. The main principle used in the experiment was the Bernoulli’s equation‚ taking major head losses into account. These major head losses were normally due to wall friction in the pipe and viscous forces between layers
