The data I have is tested at 39.15. The part that is confusing to me is that the flow rate isn't listed on the data sheet for 39.15 psi, I have the low and high injector slope in lbs/s and the min pulsewidth. Also it includes multipliers for different psi. I understand how to arrive at a new fuel pressure with the formula of (sq root(target pressure / rated pressure)) * rated flow and if the 43.5 rated pressure is truely a 42lb flow rate then at 39.15 psi it would be 39.84 lb/hr.
So I noticed that when converting the high and low slope data provided to lbs/hr (high = 43 lb/hr , low = 46.06) it does not match what I calculated from the 43.5 psi and 42lb rate. I must be missing something here and would like to figure it out just because I am curious.
Big objective here is that I need to figure the correct number out so I can create my flow rate vs kpa table and also adjust the inj pw from the 39.15 psi test data to 58.
