How multistage pump works?
493072
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.

You need to be a little more specific. \n\nAssuming you want to do some serious pumping :\n\nCan you use pumps? Yes you can. What type? The key issue is the NPSH (Net Positive Suction Head) available to the pump. \n\nIf you want a highly efficient pump, you would want to use a centrifugal type. This needs a relatively high NPSH, and also needs the flow rates to be reasonably high and the compression ratio (pressure at the outlet divided by pressure at the inlet)relatively low.\n\nReciprocating or positive displacement pumps are capable of higher compression ratios and can operate with lower NPSH but are generally less reliable and less efficient. \n\nIf you just want to pump water to the second floor or have more pressure for a shower, go to a plumbers supplier, there are any number of good pumps on the market.

What do you mean by "unload"?  An air compressor works by taking air and basically compressing it into a tank.  The amount of pressure in the tank and coming out of the lines is controlled by two different valves, the tank pressure valve and the use valve.  Both valves have limits and most equipment states how much pressure they need.  I used a compressor to spray lacquers at work.  The thicker the lacker the higher the pressure I use to make sure the lacquer spreads niceley and doesn't bubble.

I assume this is based on the principle of Osmosis. I would like a bit more data before answering further.

a simple system would be a float connected to the valve like in the back tank of a residential flush toilet.  This does not maintain precise level- the tank goes nearly empty and then spends some time refilling.\n\nprecise level control like in an chemical process situation would have a level sensor with a 4-20 milliamp output.  as the level changes, the output signal gets stronger and stronger.  The contorller opens the valve a little on a weak signal and the valves opesn more fully as the signal gets stronger.  This of course was based on a control valve to fill the tank.\n\nyou could do a similar methodolgy on a tank draining valve- as the tank fills from some other source the valve opens and lets liquid out to maintain the level.

HIGH VACUUM , u know that we can get less than 950-1000 mbar in vacuum , and normal pumps can do it , no need for extra boosting pumps to get more , in which there r no more , u can get more quantity by increasing the HP

Cleaning of the pump is called flushing.It is a technical name. It is not ordinary cleaning. Cleaning of impeller of piston or screw.Periodic flushing will improve the performance of the pump out put. Flushing can do with out opening pump.We can do it through flushing line connected seperatly in the system.

Depends on your application.\n\nPump water from a shallow (less than 20ft)or deep (greater than 20ft) well?\nHow much volume(gpm) and pressure(psi) are you looking for?\nBased on standard house current at 110VAC or off of a car battery(12V) and how long do you plan to have this pump running (few minutes at a time or hr's or day's on end)?\n\nYour question can be simple or a major under taking. \n\nA simple pump, using an old washmachine pump and motor you can come up with a basic pump. This will work on a shallow application, meaning the pump can't draw water from a resavoir being very deep, maybe a few feet. \nA sump pump is also a very shallow well type, works from a jet principle, but can't deliver a lot of pressure 10-15psi for a short period of time.\n\nWater wells which are deep, > 30ft, usually have the pump submerged into the water which then pushes the water out vs drawing the water up.\nSome of the older pumps were of a piston design, inefficient compared todays jet pump standards.\n\nOtherwise an electric moter and a mechanical pump.

Theoretically you can by compressing normal air to a tank, then you will have a full tank with a 8 bar pressure, then find another tank, do it again as you do with the first tank, and now you have two tanks with same 8 bar pressure.\nNow connect one of those tank to the inlet of the compressor and the other to the outlet of the compressor. Run the compressor, and you will get the tank that connected to the outlet of the compressor a higher pressure than 8 bar. Do it repetitively and by the end you will have a tank with 200 bar pressure.\nThis technique is used in multistage compressor.\nBut practically don't do this. Why ? A compressor is designed with a working pressure. and of course has limitation on strength.\na 8 bar compressor is much less weaker than 200 bar compressor, so with the tanks, a 8 bar tank is much weaker than 200 bar tank.

The basic theory is that if you pump steam into a place where there is a piston, the piston will move up.  Then you release the steam and the piston will go down.  You connect the piston to something to get movement, such as some gears that turn the propellers or connect them to the wheels.  It's a bit more complicated than that, but that's basically how it's done.

In order to lift the water from ground level (or below) to a certain height it has to be supplied with some energy so that it moves against the gravitational pull of the earths  gravitational force.\n                                 \n                               So here a motor acts as a device which imparts energy to the fluid(water) so that it moves to a certain height.the two  most important pumps used to pump water are centrifugal pump and recipricating pump.in a reciprocating pump there will be  a piston and a cylinder where  in the piston moves inside the cylinder whereas in centrifugal pump there will be an impeller inside  a casing which rotates and inside it and imparts energy to the fluid so that it moves up.the impeller is rotated by connecting it to the motor.hence a pump is required to lift the water.\n\n                       But pump and motor are not required for drawing water because here,the water is moving in the direction of the earths gravitational   pull.here the weight of the fluid and the direction of gravitational pull are in the same direction.so the fluid will fall under its own weight.so a pump is not required.

Hello, Every subamarine contains ballast tanks that when the needs to sink  it takes in water, due to the pressure and weight the submarine sinks and goes underwater and is propelled through propellars. When it needs to rise to suface, it lets the water out slowly and air comes and fills its ballest tanks and the submarine comes to surface. \n\nThats' it works, more info, check the web

Instead you are using fans on CPU and Video card, you have radiator boxes with a waterflow through them.\nFurthermore there is a little container with water and a pump. Water hoses connect the pump with the radiator boxes and from there back to the container.\n\nWater Cycle: Container -> Pump -> Radiator box -> Container

If the pressure is 0.76m of Hg, it is equivalent to 10.3 m of water. There is a vacuum in the tube above this water height.\n\nHowever, by “vacuum” we mean inside this space, the pressure is low. There will be vapour of water which will have some pressure.\n\nEven in mercury barometer, there will be mercury vapour inside the “Torricelli’s vacuum”.  \n\nThis is the reason that ordinary pump which sucks water from a well or sump is not able to lift water to a height more than 10m from the surface of the water.
