Investigating What Factors Affect the Efficiency of Siphoning I have chosen to investigate siphoning because as a kid I was always intrigued and puzzled by this "phenomena" when I used to clean my fish tank. The difficulty factor also played a major role. I wanted to do something which could be carried out comfortably in a relatively short time. An investigation, which is not so demanding on the practical side to allow more time for processing of the data captured. ====================================================================== On a more scientific note I am interested in mechanics of fluids. This interest was enforced last year when I had the opportunity to attend a lecture on fluid mechanics at P&G. At the conference I greatly expanded my knowledge regarding the physical aspect of fluids and their properties. In last year's AS course we have met a topic in this field. I will be applying ideas and knowledge gathered from last year for this investigation. I will also be looking at more complex concepts and ideas such as Reynolds's number, the effect of temperature on viscosity and liquid density, which we have not met in last year's course. The areas I will be looking into are as follows: 1) The effect of the Pipe Diameter on flow rate. - the effect of Pipe Diameter on liquid flow (turbulent/laminar) 2) The effect of Temperature of liquid on flow rate. - the effect of Temperature on liquid flow (turbulent/laminar) 3) The effect of the Vertical height between source and destination of the fluid on flow rate. - the effect of Vertical height on liquid flow (turbulent/laminar) 4) The effect of the Liquid's Viscosity/Density on flow rate. - the effect of Viscosity on liquid flow (turbulent/laminar) I have consulted my teachers for guidance and I have also looked very carefully into the "the Suggestions papers" which contain many possible investigations which have been done in the past. I opted to choose neither of them but many aspects I will be looking into in my investigation are similar to those in the papers.
Compared to the linear peristaltic pump and rotary peristaltic pump, the 360 degree peristaltic pump runs more slowly at the same performance. As a result, the hoses will have longer lifetime which is economic. Furthermore, the 360 degree peristaltic pump produces less friction due to the unique structure, and therefore less thermal. Especially, the 360 degree peristaltic pump has only a single compression per rotation while the ordinary pumps with numerous shoes or rollers have at least two or more compression per revolution. This means that the design of the 360 degree pump will prolong the lifetime of the tube. At the same size, this design will generate more flow volume (55%) at the same
The Trimi Tank, which was created by two hockey moms from Pittsburg, is a basic tank top that features interchangeable, removable straps as its main focus. Each tank comes with three sets of straps to layer, mix and match, or wear any strap independently. The lobster claw clasp makes it easy to remove and replace each stylish strap, which comes in various styles, such as the jewelry straps and ribbon straps. The concept for the versatile top came about during a hockey practice for their sons, which strived two best friends, Lindsay Johnson and Nikki Bilsky, to bring their business to Shark Tank.
The creation and sale of low-cost counterfeits, replicas and knock-offs of brand-name originals is a common occurrence. Across all markets, counterfeiting and Piracy account for $461 billion (OECD/EUIPO, 2016). Only 25 countries have GDPs greater than that. (Statistics Times, 2017) In the world of fashion accessories, there are many companies that look to benefit from consumers’ desires to own something luxurious while paying not-so-luxurious prices. Such is the case of Finer Bags, a company that sold what they advertised as replica or original designer brand bags. Was Finer Bags breaking the law? Was it unethical? Before attempting to answer those questions, it is best if we consider the differences between the terms counterfeit, replica, knock-off, and copy. While all represent closely copied designs of another product, the main difference
As a gazed at all the magnificent art the Montclair Art Museum contains, a painting by called Winter Spill by Philemona Williamson sparked my eye. This portrait is displayed on linen and painted with oil. The artist illustrated a black female striving to survive hectic conditions.
In the first chapter, “Sticks and Stones”, Dave Weber explains the rising epidemic of bullying among children and teenagers. Weber gives an example of his own experiences with bullying, and how his father would say, “You need to remember that sticks and stones may break your bones, but words will never hurt you,” (Pg. 1). Weber goes on to explain that harmful words can in fact result in injuries and scars. Using just your body language can result in hurt feelings. Rolled eyes, crossed arms, and sighs can throw sticks and stones. This chapter is meant to inform the audience that this book is supposed to teach them valuable lessons.
A representation of the slow decrease in flux that can result from consolidation of the fouled layer is presented in figure 2.4.
Pipefitting is a good trade; it is a very common job in Eastern Kentucky. It is fairly easy to become one in Kentucky. Most of the time a pipefitter is carrying on from his/her family, say that it has been going on for generations and they just keep it going.
In order to determine a system curve the flow rate must be determined at a range of points. Plotting both the system curve and pump curve together enables the operating point to be found which corresponds to the ideal flow rate. The pump curve can be determined experimentally by modifying the system curve one of two ways; either opening a valve or changing the height difference.
Question: Discuss the importance of Relief Valves in the unit operations in detail, and give the design criteria/ parameters/ models available equations in the literature. Support your work by giving a typical example from the literature.
Keeping gutters clean and functioning can have a significant impact on the longevity of a roof.
In industry, the performance specifications for a particular pump may be known, but the tests are usually based on water as the pumping medium. For liquids of significantly higher viscosity than water, these performance curves may only be accurate at certain flow rates, or they might not be valid at all, and it might be necessary to recalibrate the specifications for higher viscosity liquids.
...he principle numbers of Froude, Reynolds and Weber. Mathematical model predicts the heat and mass transfer in numerical framework for both transports phenomena of relevance to the industry continuous casting tundish system. Additionally, it has an excellent agreement outlet temperature respond the step input temperatures in the inlet stream of water in the tundish model. The simulations of 8x8 grid and 16x16 grid are applied to obtain significant difference between the TAV maps in which both grids are computed by software represent the specific flow of the fluid in the model and the steel caster as the actual size system. Therefore, the physical and mathematical modeling is used as a guidance to build a model before the prototype is constructed in terms of calculation, measurement and determination of specific fluid flow, heat and mass transfer in the water model.
From the graph 2, it is seen clearly that the relationship between purity and boil-up rate is inversely proportional to each other. In order to achieve a good separation and high purity between the liquid and the vapour must be brought to an intimate contact by counter-current flow. Increasing the vapour flow actually means decreasing the interaction time between the down flowing liquid and up flowing vapour inside the column. Hence, if ...
CFD analysis is widely used in industries like any industrial process involves heat transfer and fluid flow. Some of the examples are as follows:
Suction and lift are paramount contemplations when pumping liquids. Suction is the vertical separation between the liquid to be pumped and the core of the pump, while lift is the vertical separation between the pump and the conveyance point. The profundity from which a hand pump will suck is restricted by air weight to a working profundity of less than 7 meters. The depth to which a hand pump will lift is administered by the capacity of the pump and the driver to lift the weight in t...
