Here is the math I used.


33:1 AFR
100kPa Intake pressure
4.75 lbs/min total air
0.144 lbs/min total fuel or 65.41 grams/min total
65.41 grams/60 to get seconds = 1.09 grams/sec total for all four cylinders

2800rpm/2 = 1400 cycles per minute
1400/60 = 23.33 cycles per second
1.09grams/sec / 23.33 = .0467grams for 1 cycle all four cylinders
.0467grams/4cylinders =.0117grams for one cylinder and one engine cycle.

I then used a calc online for compounds and it converted .0117grams to 0.01 milliliters for petrol. I then looked up IV gtt numbers and found that 11 drops = 0.55ml.

I tried to simulate the IV drops so its probably not to the gnat's ass lol
