Sad  Stoichiometric ratio calculation for JP 5000
Dear Technocrats

I am working on HVOF sprayed coatings, especially using JP-5000 torch. I have read that to decrease the particle temperature at roughly constant velocity, stoichiometry is shifted to higher side. I would like to calculate the stoichiometric ratio for following Fuel and oxygen flow rates :
1) Kerosene - 18 slph , Oxygen 1700 scfh.
2) Kerosene- 20 slph, oxygen 1900 scfh.
3) kerosene- 22 slph, oxygen 2100 scfh

Please anyone help me. I really need to understand this term.Question

regards

1 SCFH = 0.4381 NLPM.

1700 scfh is 12.41 NLPH

THANKS FOR REPLY DEREK,

What is the relation between SLPH and NLPH ? I have seen in one thread (by author Metallurgy_eng) of this forum that JP-5000 manufacturer have designated O2= 800 slpm and fuel = 20 lph combination to lambada=1 (o2/fuel).
Please throw some light on this point also.

regards

TAFA has 275 scfh of O2 to one gallon of kero

or

2056 liters to 1 liter kero

I think most use 2.118 for the nlpm to scfh conversion.

nplm is metric and 0*C at 1 atm
slpm is 21*C at 1 atm - usually... it can be 20*C as well
