Flow through pipe in parallel Example :Two pipes connect two reservoirs (A and B) which have a height difference of 10m. Pipe 1 has diameter 50mm and length 100m. Pipe 2 has diameter 100mm and length 100m. Both have entry loss kL = 0.5 and exit loss kL=1.0 and Darcy f of 0.008....
it is truly amazing to note the role played by conduits in transporting fluid. For example, the water in our homes is normally conveyed through pressure pipelines, from the distribution system, so that it will be available when and where we want it. Moreover, virtually all of this water le...
(seeFigure 5A), which may be inserted into the pipe proper. If the velocity at point P, where the tube has a cross-sectional areaAP, isvPand the velocity in the constriction, where the area isAQ, isvQ, thecontinuitycondition—the condition that the mass flowing through the pipe per unit...
Thus, experiments involving measurements of pressure gradient as a function of flow rate in pipes offer an opportunity for students to visualize and quantify entropy generation in real processes. In this article, the background in fluid mechanics and thermodynamics relevant to the concepts of ...
In order to visualize the flow through pipes, cut planes are created. The cut planes at 85%, 90% and 95% positions are created. A fourth cut plane is created to YZ plane where the complete flow through the pipe can be visualized. For all these cutplanes, the visualizing parameter chosen...
The presence of water must be properly accounted for when designing and predicting the flow behavior in both wells and pipelines. Numerous studies have been published in recent years in oil–water flow through pipes. This paper reviews research achievement and current trend in order to offer a ...

into thermal energy. This results in a decrease in the liquid velocity and a decrease in the liquid pressure. Flow of incompressible liquids through pipes is described by the mechanical energy balance, Equation 1, combined with the incompressible fluid assumption, Equation 2. The net result is (...
Figure 3. In noncircular pipes, the trivial laminar flow becomes unstable at a critical pressure gradient. Experimentally, a direct transition to turbulent flow with large amplitudes is observed, according to the fact that in general at the instability point of the trivial solution a subcritical ...
