Relation of pressure & RPM in pump

[davisdony]

Any one know the relationship between pressure
and RPM in pump



I know that it is directly proportional. do any one have some calculation on it



I want to design a 1bar pump

is there any standard pump available for reference

do any one can do some sort of help so that I can improve upon that

does any one have some model of pump of 1bar



any sort of help or suggestion or discussions are welcome

There is more to it than that. Presure, and flowrate is what is used to caculate work or Horsepower. Look it up on Wikipdedia and it will explain it all. RPM is not a factor. You can gear the pump to any RPM. Also there are fixed displacement pumps and centrifugal pumps. You can design a 1 bar pump but what determines the size is the flow rate. A six foot pump or 2mm pump both can produce 1BAR.

I will tell my requirements

I want to pump liquid from one liter bottle.

It is a very miner action, Cost is the main factor

it should be very cheep so that the product cost will not go up

also the size

it should be very light so that the person carries the product hardly notice
some difference



hope you can suggest me with some links or something else

already available pumps are also ok
