what are centrifugal blowers?

"Centrifugal blowers move air by means of the centrifugal force generated by rotating a cylindrical runner on which blades have been arranged.\nCentrifugal blowers have a small outlet, which concentrates air in a single direction, and thus are used for local cooling. They also create large static pressure, making them optimal for cooling equipment through which air cannot flow easily and for airflow through ducts."

OK, a rotery vane pump consists of 2 concentric circles.  The circle in the center is spinning 'round and 'round and the space between the two circles is divided up into chambers.  The fluid enters one chamber that is rotating around and it gets transported to the other end of the pump.  This in itself is an OK design for a pump, but the inventor of the rotary pump had the genius to place the inner concentric circle just a bit off center so as the chamber nears the end of the pump, it gets smaller and smaller.  This increases the pressure on the fluid and gives it a little extra squirt.\n\nThe centrifucal pump is sorta like a fan.  The fluid enters the center of the pump (this pump is also a cylander) and there is a rotating fan of bars inside the pump.  As the bar rotates, centrifical force moves the fluid toward the outside of the pump and out of it.

An impulse turbine is one where water flows out of a nozzle and hits the turbine blade to give up its kinetic energy.  A "Pelton wheel" is an example of an impulse turbine.\n\nA reaction turbine reacts to the flow of the water past its blades.  It doesn't have a jet nozzle, the turbine is just set in the water flow.  A "Kaplan turbine" is an example of a reaction turbine.

Wind Generator:\nA wind turbine is a machine for converting the mechanical energy in wind into electrical energy. If the mechanical energy is then converted to electricity, the machine is called a wind generator.\n\ncheck out the following:

Multistage pumps are genrally centrfugal pumps. They are stacked in series- That is outlet from one is connected to inlet of the second one, and outlet from second is conncted to inlet of third and so on.

Gyroscopics.\nThe wheels act as gyroscopes.  Precession causes any tipping to appear to the rider as a change in steering, which the rider finds easier to control using the handle bars.  Motorcycle riders use this effect by leaning over to one side to help change directions.\n\nWhether there is or isn't such a thing as "centrifugal" force depends on whether you are in a linear or a rotational frame of reference.

Static pressure is usually associated with the pressure inside a vessel or duct. When your air conditioning at home kicks on, the blower builds up static pressure in the ductwork. The registers blow out air because of this static pressure relief through them.

look at grainger.com for a dual action air cylinder, (probably 1/2" diameter x 6" stroke), also look for a manual control valve.\nadd an air compressor and it's almost built for you.\n\nmake sure to add some guards as the air cylinder will deliver at least 500 lbs force

the air at the path of the rotating blade of the fan is forced to flow. pressure is directly proportional to the speed of the fan blade

There is no such thing as "centrifugal" force.\n\nThe mud stuck on a rotating wheel is undergoing circular motion.  At any instant in time as the wheel rotates, the mud stuck on the side has a velocity vector pointed straight outward tangential to the wheel...and yet it still goes around in a circle.  Since the velocity is constantly changine, since the direction is constantly changing ("speed" may or may not be constant), there must be some type of force acting on the mud to cause it to accelerate.  This force is called centripetal force, the force causing the mud to contantly accelerate toward the inside (axis of rotation) of the wheel.\n\nThis foce is not magic, something must be applying the force on the mud.  You could call it the "stickyness" factor of the mud or a type of friction adhearing the mud on the wheel.  In reality, it is due to thesruface tension of water [but that is a topic for another day].\nThis centripetal force is applied on the mud so that is experiences centripetal acceleration causing the musts velocity to constantly change as it goes around the wheel, without this force, the mud would just fly off in a  straight line.\n\nAt some point, when the wheel is turning fast enoug, not enough centripetal force is being applied to the mud in order to keep it adhearing to the wheel and continue going around in a circle.\nCentripetal force = m(v^2 / r),\nwhere m is the mass [of the mud], v is the tangential speed [of the mud], and r is the radius of the rotation.\nAs you can see, a larger centripetal force is required if the wheel is spinning very fast, so if the wheel is spining so fast that the mud does not get enough centripetal force, it will fly off.  Another fact would be a smaller radius of rotation, the smaller the radius, the higher the force needed.

In a rotary air compressor, there is a spinner and the air comes into the middle and gets spun to the outside.  It builds up a velocity as it moves faster and faster toward the circumference of the spinner assembly, until it hits the outer housing and gets squashed as it hits until it escapes thru an outlet tube.  When it squashes, the pressure rises, giving an outlet pressure higher than the inlet pressure, i.e. compressed air.
