Pipes: Annotated Plumbing System

In this lab new equipment was used such as the electronic balance, the pipet, and the graduated cylinder. Some of the different techniques that were used in this lab were the water displacement technique and the filling of the pipet. The two different tables that were used in this lab were the Qualitative data table and the Quantitative data table. In the Qualitative table there were only observations and no numbers. In the Quantitative table numbers were used. In this lab there were some formulas that were required. The formulas included density, water displacement, specific gravity, and percent error. In this lab percent error was also used. Percent error is used to determine the accuracy of the calculations acquired in the

everyday uses. This network of piping used daily must be properly managed and planned for, as

This project is on building a pipe bench. Most people have no idea what this is. Well simply put it is a bench that is a combination of wood and metal piping. This way the bench has a sturdy frame and unique look. Most benches are either wood, or metal. These benches are set up for the best of both worlds. Most wooden benches just aren’t as durable as an iron/metal bench. Also lost is the comfort factor with most metal benches. The idea of a “pipe bench” is all around a great idea.

This experiment is designed to facilitate an understanding of the principles involved when water flows through a pervious material such as soil.

Many people have flocked to the industry lately, due to the belief that there is a lot of money to be made there. So, many have decided to get certification in plumbing. The certification is pursued because it is regarded as illegal to do your own plumbing in certain countries. They eventually open their own businesses and hopefully provide good plumbing services to their clients. They can either focus on residential plumbing or commercial plumbing such as at local restaurants. Persons who have some plumbing skill by learning it on their own through DIY books are able to perform many fix it plumbing jobs in their homes. There many do it yourself books available at bookstores.

As shown in figure 1 , schematic diagram of the experimental apparatus is shown. The three pipes used in the fabrication of the heat exchanger are made of brass(inner pipe), copper pipe(helical pipe), mild steel pipe(outer pipe). The inside diameters of the three pipes are 0.03175m, 0.009525m and 0.0635m respectively with thickness of each pipe as 1.5mm only. The experimental set up is composed of a test section, normal water loop, cold water loop, hot water loop and temperature measuring system. The water is used as working fluid. The test section and the connections of piping system are designed such that parts can be changed for different flow arrangement. The hot water loop consists of a storage tank, an electric heater of 3000W immerged inside the storage tank to obtain the high temperature of hot water, a pump and gate valve. The cold water loop consists of a storage tank, a pump and gate valve. Ice cubes are used to cool down the temperature of tap water to nearly 130 C . The normal water loop consists of storage tank, pump and gate valve. After the temperature of the water is adjusted to the desired level, the normal, cold and hot water are pumped out of the storage tank and are passed through test section and discharged to outside. The flow rate of the water are controlled by adjusting the valve and measured by the flow metres of +_ 0.2% of full scale. The heat exchanger is a concentric tube

The model validation is based on the observation of some quantities of interest as the pressure, the gas mass fraction, the enthalpy flow rate, the torque, etc. These outputs are computed using LSODAR \footnote{Short for Livermore Solver for Ordinary Differential equations with Automatic method switching for stiff and nonstiff problems, and with Root-finding \cite{Hindmarsh}.}, a variable time-step solver with a root-finding capability that detects the events occurring during the simulation. It also has the ability to adapt the integration method depending on the observed system stiffness.

According to the flat plate collectors that were install on houses in Cyprus, the aim of this investigate project is to produce several different ideas of how the water temperature will be increased when it exiting a pipe of the collector. Also some tests will be made in computational fluid dynamics (CFD) software to come across with the best idea and an efficiency curve will be generated.

2004). At the completion of the first catchment simulation, the majority of the water in sponge was removed, and 1000 millilitre tube topped up with water to have exactly 1000 millilitres. The repeat of this simulation was to have a plastic A4 sheet placed on the sponge to represent an urban catchment, and the same process was implemented. To keep the simulations fair and balanced, the roles in the experiment have to be consistent, and the motion in which the water is deposited needs to be kept nearly identical.

The largest weakness in this paper, however, is the lack of experimental data available. While a “validation experiment” was conducted in a scaled-down (1:10) high-altitude-test facility, the only results taken from this experiment were static pressure and static temperature at various locations. [1] The remainder of the results presented were purely computational. Without experimental benchmarks for comparison, it is hard for the reader to determine the suitability of the chosen computational models. A computational experiment becomes significantly weaker when it lacks experimental data to support the chosen numerical methods. The paper would have been much stronger if both the SA model and k-model were used for the entirety of the trials and a physical experiment

For model validation purpose, Particulate Solid Research Inc. (PSRI) and National Energy Technology Laboratory (NETL) organized the modeling competitions in the form of third Challenge Problem []. By providing the geometry of a circulating bed and operating parameters for different conditions, the organizers asked modelers to predict the hydrodynamic characteristics without prior knowledge of test results. In third Challenge Problem, the CFD models did better than their performance in first and second challenge problems organized by PSRI. One of the issues in model mismatch was the high computational time required to reach the steady state of the fluid bed process. Other mismatch was partly due to modeling only the riser section rather
