the pressure drop of a fuel valve needs to be measured (tested). one end of it is a bellmouth and the other Gamah fitting. the flow rate in 120 gpm. searched online and could not find a lab. anyone have some info?

RE: testing lab

Does it have to be tested with fuel, or could you test with a more benign fluid and use that data to estimate the dp with the fuel?

What kind of fuel, i.e. volatile like gasoline or propane, or low volatility like diesel or bunker oil?

Southwest Research Institute, http://www.swri.org/4org/d18/mechflu/multflo/fctf/ does what you are asking for, but it's not cheap.

RE: testing lab

jet fuel. JP-5, JP-4. or substitute with stoddard solvent.
i will contact SWRI.

RE: testing lab

Do you need "a" number, or do you need "the" number?
Sometimes, the quick-and-dirty test you can do yourself is good enough to answer the question that's being asked.
Setting up and running the test yourself often gives insight into the function of a device that you can't gain by hiring someone else to do it.
Also offers the flexibility to chase down the cause(s) of unexpected results without doubling the cost of the test.
Not meant to replace the authority of a reputable test laboratory with the right apparatus following a well-planned procedure, of course.


RE: testing lab

Most acceptance or calibration flow test stands are set up for a particular fluid. Flow test stands for military jet fuel (JP-5) system components probably use something like MIL-PRF-7024.

A fuel system test bench capable of flowing 120gpm is probably not common. So if you don't have any luck with SWRI, you might try contacting a couple of the companies that build/service aircraft fuel system flow benches such as Testek or Staley to see if they know where you can find one.
