### Centrifugal pump - Saylor.org

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.[1] 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:[2] 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...

2014 GMC sierr a. To engineer our most dynamic and advanced pickup ever, we didn’t limit ourselves to the usual truck innovations. For the all-new 2014 Sierra, we ventured far beyond the automotive category to discover some incredible technologies. For our new available Safety Alert Driver Seat, we’re utilizing haptic sensory feedback to alert drivers through their sense of touch. Twenty-first century, smart-grid power generation that conserves energy when demand is low, then makes more when it’s needed, was the inspiration for our new EcoTec3 engines that offer abundant power and efficiency.1 And why should fighter pilots be the only ones to benefit from touch-screen technology? In Sierra, they aren’t. Discover how these and other innovations make the 2014 Sierra more than just a truck. It’s incredible thinking in the form of a truck. That’s Professional Grade. EPA-estimated 16 city/23 hwy mpg (2WD), 16 city/22 hwy mpg (4WD) with the optional 5.3L V-8 engine.

2014 Chevrolet Silverado 1500 with 2-Speed Transfer Case RPO Codes NQG, NQH 2014 GMC Sierra 1500 with 2-Speed Transfer Case RPO Codes NQG, NQH Some customers may want to tow their vehicle behind another vehicle with all four tires on the ground. This is referred to as flat, dinghy towing or even as a “toad” (slang for towed vehicle). Towing in this manner is acceptable only on certain 4WD trucks depending on the transfer case option. The vehicle should be properly equipped and prepared as described below. The information contained in this bulletin supplements the Owner’s Manual. Please provide a copy of this bulletin to customers that want to dinghy tow their truck. Towing Set Up Procedure Notice: Use extra care whenever towing another vehicle. Do not exceed the towing vehicle's ratings such as the gross combination weight rating (GCWR) by adding the weight of the dinghy towed vehicle or vehicle damage may result. Recreational/Dinghy tow basic setup procedures Four wheel drive pick-ups with a two speed transfer case (that have a neutral and a 4 low position): 1. Tow only in forward direction. Position the vehicle to be towed behind the towing vehicle. 2. Securely attach the vehicle to the tow vehicle. 3. Firmly apply the parking brake, start the engine and shift the transmission to neutral. Caution: Shifting the transmission to neutral can cause the vehicle to roll and may cause personal injury. 4. Shift the transfer case to neutral. Caution: Shifting the transfer case to Neutral can cause the vehicle to roll, even if the transmission is in park (automatic) or 1st gear (manual), and may cause personal injury. 5. Check for transfer case neutral by shifting transmission to reverse then drive and verify there is no engagement. 6. While the transmission is in drive, turn the ignition key to Accessory. Copyright 2013 General Motors LLC. All Rights Reserved. 7. Shift the transmission to Park. 8. Depower the vehicle by removing the negative cable at the battery. This procedure must be followed or the steering column could be damaged. • Cover the negative battery post with a nonconducting material and prevent any contact between the negative battery terminal and the negative battery cable. Notice: If power is provided by accidental contact of the cable and terminals, damage to the towed vehicle may result, which would not be covered under the New Vehicle Limited Warranty. 9. Verify the steering column is unlocked. 10. Release the park brake only after verifying the towed vehicle is attached to the towing vehicle. 11. The ignition key must remain in the towed vehicle. Manually lock the doors and use 2nd key for access. Disconnecting the Towed Vehicle 1. Leave the truck connected to the tow vehicle. 2. Connect the battery. 3. Set the parking brake and place transmission in Park. 4. Shift the transfer case to 2 HI. 5. Disconnect the truck from the towing vehicle. 6. Reset any lost ...
