[NSRCA-discussion] Fuel line question-Data

[Rcmaster199 at aol.com]

Vicente,

Chris' data is perfectly valid regardless of whether one uses a pump. It is 
simply the flow possible (maximum flow) in each type of fuel line under each 
level of pressure. You can standardize each flow in terms of ozs/min to see the 
differences the get a feel for the flow capacity under each set of conditions.

The whole point is that no Pattern engine uses anywhere near the flow 
capacity of each set of conditions tested. Therefore, a medium sized line will have 
the required capacity to feed the typical Pattern engine.

Can someone explain what the data means?  I assume that is the time to move 
14 oz out of the tank.  In the first test, the tank is empty in 2 min 15 sec 
using the medium fuel line.  The time is reduced to 1 min 30 sec using the large 
fuel line.  As we can see the flow is very high compared to the actual flow 
we use.  Around 14 oz in 10 minutes.  Furthermore, we use fuel pumps so the 
actual difference in pressure drop are not affecting the motor.  Therefore, I 
think this information is valid for non pumped engines.  In other worlds, I don't 
think that the diameter of the fuel line will help too much in pumped engines 
unless the lines are very long.  I don't think is the case in the standard 
set up we use for pattern.

Have a nice weekend,

Vicente Bortone

Real data - great.
Thanks,

Here is some tests I performed, you might find interesting. Chris
