Tmoose, thanks for the information. I am however, well aware of the mechanics behind automotive fuel system (automotive systems for that matter), just not the physics behind them.
Due to difficulty in finding any information on the actuall design specs of fuel pumps in use these days I'm now...
Does it seem reasonable to assume that an automotive fuel pump will operate in the range of 1500 to 2000 RPM? or are the vane's much for efficiant as to facilitate sufficient flow rates at between 500 - 1000 RPM?
I originally began asking this in the automotive forum but its come to my attention that this forum may be more appropriate. I working on a computer simulation of the pressurization of a fuel system by its fuel pump and fuel pressure regulator.
At this point I'm decided that I need to figure...
OK, please correct me if I'm wrong but I was under the impression that most automotive fuel pumps were vane type. Are there also centrifugal type automotive fuel pumps?
At this point I'm also thinking that I should be targeting the forces created by the pump versus the forces exerted by the...
Ok, well I plan to use this information in a quick and dirty computer simulation before I put it to practical use and I need to figure out how to get some numbers out of this problem. I am aware that there are several types of pumps such as vane, centrifugal, flex impeller, diaphragm, etc. My...
Actually I've managed to come up with another theory that I'm having trouble finding the information need to confirm it with.
The fuel pump creates no real pressure itself... The only pressure actually measurable imediately following the pump is the pressure created by the liquid itself while...
For as mush as I can tell, you've completely answered my questions. Thanks. I actually may have a few more but with the information you've given I may be able to figure the rest out myself.
In a perfect world a certain in-tank fuel pump will flow 200 liter/hour and read 40 PSI on pressure gauge connected to the outlet of the pump.
Now for 2 scenarios...
The fuel tank is nearly empty and not moving, there's only enough fuel in the tank to cover the inlet of the fuel pump...
