Nozzle sizing /Flow rate

[miata_rp]

Hello to Everyone,

Hi Richard, I recently viewed this post regarding the approach to use in sizing a nozzle for turbodiesel applications.
Am I correct in understanding your computation which implies 3% of mass air flow is a good starting point? i recently
installed a water injection system using aquamist nozzles and pump on a Toyota 2.4 turbodiesel with .8 bar(12 psi boost).


11.2 kg/min=395 oz./min; a 1 mm nozzle flows 11.6 oz/min; 11.6/395 oz min ==3% of mass air flow

My 6.5L turbo diesel flows a little over 400 CFM. What nozzle size would provide an appropriate water flow rate at maximum load? Since I have a tough time with metric conversions I would appreciate knowing the nozzle water flow rate in either oz/min. or GPH."

Richard L:

1. 1 cu ft per minute = 0.028cu m per minute
2. 400 cu ft = 11.2cu m per minute
3. 1 cu m of air weights 1Kg at 25C
4. so 400 cu ft per minute is 11.2Kg per minute.

1mm nozzle flow 330cc/min (aquamist pump) or 11.6 oz/min
