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

Both laminar and turbulent flow regimes are to be studied. Equipment: Air valve Water manometer Mercury U-tube Isolating tap meter From water supply Needle valve Test tube Figure 1 Pipe friction apparatus A. Laminar Flow The laminar pipe friction apparatus is shown above. It consists of a water loop. The

Introduction: In any pipe system there is going to be a loss of energy due to the effect of viscosity from a fluid acting upon the surface of the pipe‚ this is called Friction Loss. This type of lost depends on the shear stress due to the walls of the pipe and the fluid. It also depends in weather the fluid is laminar or turbulent. A major difference between these two flows is that due to a viscous layer created in turbulent flow the roughness of the pipe can be taken in account while in laminar

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

ABSTRACT The quality of pipe borne water supplied by Imo State Water Corporation has been assessed by analyzing samples of water collected from different locations for their physicochemical parameters and bacteriological quality. The observed values were compared with standard values given by the World Health Organization for potable water .The quality of the analyzed water is found fit for human consumption.

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
