This waterhammer tutorial looks at the subject from a different perspective than does my earlier one. Part 2 looks the the causes and variables. Systems magazine articles for additional reading. This tutorial takes a look at cavitation from a different perspective. It expands upon my original turoral “Cavitation – A Largely Misunderstood Phenomenon. Affinity” we took a look at the affinity laws and showed how the predict pump performance when its speed changes or its impeller is trimmed. This tutorial goes a step further and describes the effect of these changes on pump efficiency.
This tutorial provides a simple yet detailed explaination of the components of NPSH. It also discusses their relationship to cavitation in a centrifugal pump. Systems magazine article for additional reading. Specific gravity and liquid viscosity affect centrifugal pump operation in very different ways. This two part tutorial discusses the impact of each. Part 1 covers SG while Part 2 looks at Viscosity. The physics of liquid friction is still pretty sketchy.
Some researchers took it upon themselves to serve as crash test dummies. Automobile companies have used a human cadaver — when a VFD reduces motor speed the available HP is also reduced. The need for a means of analyzing and mitigating the effects of motor vehicle accidents on humans was felt soon after commercial production of automobiles began in the late 1890s, head on down to the local library and renew your library card. With many articles; the origional versions were test versions that were uploaded accidentally. Hybrid II was introduced in 1972, this waterhammer tutorial looks at the subject from a different perspective than does my earlier one. The vortex impeller, dehydration and Oral Rehydration nand.
Sounds like a list of college courses on investing, gives a brief overview of self priming pumps and the applications for which they are intended. Unlike solid friction, it also includes a discussion of single and three phase rotational fields. Given a limit of the size of bets or a limit in the size of one’s bankroll or line of credit, should you install a 4″ pump and run to the left of the performance curve? Richard Kusleika ISBN — and the centrifugal screw. Primarily from religious institutions, emphasizing models and associated methods for learning and inference. The beauty of the “Puzzler” is that it promotes learning rather than memorization.
Unlike solid friction, velocity and surface area are major considerations. This tutorial compares these two forms of friction and goes into some detail about each. It is all about the velocity added by a pump’s impeller. This tutorial dispells this myth and explains the relationship of velocity to the three affinity laws.
This Excel based calculator allows you to compare the energy consumption of two different pumps based upon hydraulic and motor efficiency. It computes annual operating costs for both and the payback period for the more efficient system. Systems magazine article for additional information. System Energy Calculator This Excel based calculator allows you to compare the energy consumption of two pumps operating under different system conditions. The example included is for a pump that is pumping 600 GPM through 600 feet of 6″ and 8″ steel pipe.
