Converting Bars to Liters per Minute

10/21/2009 10:44 PM

Is there a formula for converting pressure 1bar to liter per minute ?

Many thanks in advance....

No. There is no formula.

Huh!? Bar is a pressure as you said; liter per minute is a flow rate. They ain't the same--they measure different things. Like lynlynch said NO.

Unless maybe you want the flow rate thru an orifice caused by a given pressure. But you didn't say that.

The indicates that you may be onto something else.

To afford you a scientific answer you must give more information.

How many seats in the bar?

What is the temperature? (the flow rate may be proportional to temperature )

During which game?

What liquid?

I real life we would have to know length and diam of piping, size of emitter (orifice , nozzle) etc . Then there will be formulas.

Enlighten us on your requirements and we may respond.

"How many seats in the bar?"

GA! I've been under lots of pressure in bars when faced with consuming even fractions of liters per minute before they closed.

Doesn't convert. Pressure is force per unit area. Liters per minute is volume per unit time.

Is there any further information you may have which would assist us?

You may need to consult Mr Bernoulli, Mr Reynolds, or the pump manufacturer's characteristic chart, depending upon what your pressure source is, and what sort of network it's travelling down. The nicest polynomial flow relationship will always be subject to a pump's fixed delivery curve.

That doesn't seem to make sense - how does one convert pressure to volume flow rate? Go back to your fundamentals, P: [M][L]-1[t]-2 vs Q: [M]3[t]-1 - the two don't match up.

Check your problem/application again - have you got all the information you need?

Is this oil flow in barrels per day?

Or, beer guzzled during a foot ball game in one bar?

Yes, you use the same formula that you use to convert eggs to oranges.

Hi Guest,

I assume you refer to perhaps the pressure and flow through a shower? Or the 'head' of water needed to get a particular pressure?

1 Bar = 14.7 psi which is a force or pressure measurement. While,

1 Litre = Is a linear or flow/volumetric measure over time.

This site just below lists a series of Conversion Tables on the left, then the measurement you are converting it to in the centre, then the conversion factor on the right. As an example here is just a small portion:Remember, work only from left to right

You will have to work out what the flow through whatever size pipe you have.

(Come on I am not doing all the work!) And below is my home made flow chart.

I have started low, with a flow that is little more than a trickle through an 12" (13mm) pipe

I have figured out an approximate chart for, US Gal/min, Imp Gal/min, Litres/min.

Hi Guest,

I have no idea who you are but, throwing a suggestion like that into this thread is completely useless!

Hi Guest,

I and others have written in and given suggestions and facts. Where are yours?

As a first suggestion, to make yourself even more famous than you already are, why not join CR4 and as a Member reap the benefit of your notoriety.

Or could you not take the criticism that Membership would bring?

Go on, explain to a simple ignoramus like me how bars (14.7 psi) are linked and can be cross referenced with LPM (Liter per Minute) without knowing the pipe size first, in any meaningful way. I can't wait to hear what you have to say.

Though a newer metric system now predominates.

You have the world at your fingertips to either insult, like you did me, or to make an amazing discovery.......................

Take care. Oh, Every insult meant where not indicated!

This forum needs more people like you, babybear, who are willing to assist, and to do so in a positive way.

Good job.

Hello standarded,

I appreciate your candour my friend.

It is not a case of me knowing it all. Rather an idiot throwing names around for no good reason.

If they want to do that, and act the arse, they can go to some other socially interactive site, not here.

I like to think if it was not me, then another Member would have slapped the wrist of this very silly person?

Take care and many thanks for your kind remarks.
