Centrifugal pump A centrifugal pump is a rotodynamic pump that uses a rotating impeller to increase the pressure of a fluid. Centrifugal pumps are commonly used to move liquids through a piping system. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from where it exits into the downstream piping system. Centrifugal pumps are used for large discharge through smaller heads. History Warman centrifugal pump in a Coal Handling and Preparation Plant (CHPP) application According to Reti, the Brazilian soldier and historian of science, the first machine that could be characterized as a centrifugal pump was a mud lifting machine which appeared as early as 1475 in a treatise by the Italian Renaissance engineer Francesco di Giorgio Martini. True centrifugal pumps were not developed until the late 17th century, when Denis Papin made one with straight vanes. The curved vane was introduced by British inventor John Appold in 1851. How it works Like most pumps, a centrifugal pumps converts mechanical energy from a motor to energy of a moving fluid; some of the energy goes into kinetic energy of fluid motion, and some into potential energy, represented by a fluid pressure or by lifting the fluid against gravity to a higher level. The transfer of energy from the mechanical rotation of the impeller to the motion and pressure of the fluid is usually described in terms of centrifugal force, especially in older sources written before the modern concept of centrifugal force as a fictitious force in a rotating reference frame was well articulated. The concept of centrifugal force is not actually required to describe the action of the centrifugal pump. In the modern centrifugal pump, most of the energy conversion is due Cutaway view of centrifugal pump to the outward force that curved impeller blades impart on the fluid. Invariably, some of the energy also pushes the fluid into a circular motion, and this circular motion can also convey some energy and increase the pressure at the outlet. The relationship between these mechanisms was described, with the typical mixed conception of centrifugal force as known as that time, in an 1859 article on centrifugal pumps, thus: Centrifugal pump To arrive by a simpler method than that just given at a general idea of the mode of action of the exterior whirlpool in improving the efficiency of the centrifugal pump, it is only necessary to consider that the mass of water revolving in the whirlpool chamber, round the circumference of the wheel, must necessarily exert a centrifugal force, and that this centrifugal force may readily be supposed to add itself to the outward force generated within the wheel; or, in other words, to go to increase the pumping power of the wheel. The outward force generated within the wheel is to be understood as being produced entirely by the medium of centrifugal force if the vanes of the wheel be straight and radial; but if they be curved, as is more commonly A centrifugal pump uses a spinning "impeller," the case, the outward force is partly produced through the which normally has backward-swept blades that medium of centrifugal force, and partly applied by the vanes to directly push water outward. the water as a radial component of the oblique pressure, which, in consequence of their obliquity to the radius, they apply to the water as it moves outwards along them. On this subject it is well to observe that while the quantity of water...
If you live in an apartment or condo and dream of cozying up by the fire, there is an ideal solution: an electric fireplace. The warm, radiant heat of today’s electric fireplaces can be purchased at the store, carried home in the back of your car and installed in minutes.

And with realistic fire technology that rivals a wood burning fire, the end result is snap, crackling great! BEAUTIFUL FIRE FOR WARMER CLIMATES Electric fireplaces make having a fire possible no matter the time of year…and, for just pennies a day. On a warm night, simply turn on the fire – minus the heat – and in seconds you can be basking in the glow of the fire while still sitting in your shorts. Then, when evening temperatures dip, turn on the heat option to take the chill off. Electric fireplaces work well in colder climates, as well. With variable heat controls, you can create enough heat to warm your toes or crank it up to keep a 400 square foot space at a comfortable temperature. And, because it requires no venting, an electric fireplace is perfect for locations where installing a fireplace is tricky, such as basements. those who desire a more traditional design, there are electric fireplaces that mimic wood or gas burning fireplaces, complete with mantel, fireplace surround and doors.

Society’s Grand Challenges Insights from Psychological Science As a society, we face many challenges, and we depend on science to help. Whether we seek to halt global climate change, cure devastating diseases, reduce crime, end poverty, diminish health disparities, or achieve vitality in old age, advances in modern science are expected to help. The science of psychology contributes to deeper understanding of these and many other societal challenges. The American Psychological Association is devoting significant resources and energy to bringing the best of psychological science to the forefront. In partnership with other fields of science, solutions will be found. This booklet is one in a series, examining the insights of psychological science into challenges facing society. Each booklet focuses on a key challenge, provides a sampling of what we currently know, and suggests promising avenues for future research. The published work of scientists is cited, so that readers can learn more on their own. We indeed face many challenges, and together we can solve them! Alan E. Kazdin 2008 President American Psychological Association 2 3 GLOBAL CLIMATE CHANGE Most scientists recognize that human behavior is the main cause of today’s climate crisis. Understanding that behavior, and learning how to change it, is one of our best hopes for a solution. Whether the goal is to reduce carbon emissions or to help vulnerable populations deal with rising sea levels and changing weather patterns, it is clear that values, beliefs, thoughts, and social relationships are key. According to the 2007 report of the Intergovernmental Panel on Climate Change, however, human behavior is one of the least well understood components of the climate system. That is where the science of psychology can help. By itself, psychology cannot stop global warming or deal entirely with its consequences. Other scientific disciplines provide the expertise to model climate change, build more efficient power plants, and predict the impact of carbon taxes on economic development. What psychology can provide is an e x pl a nat ion for why people choose to i nst a l l energ yef f icient appl ia nces, reduce gasoline consumption or support government policies aimed at addressing climate change — and why, despite the best of intentions, they often do not.
