formules, conversions et abréviation utiles

[tru]

quelqu'un aurais quelque formules interessante a posté ici? moi je vais commencer par ceux que j'ai pu trouver par ci par la.. a vous den ajoutez

-----
1 atmosphere = 14.7 psi
1 atmosphere = 101.3 kPa
1 atmosphere = 1.013 BAR
1 BAR = 14.51 psi
lbs/hour = Cubic centimetres (cc) per minute / 10.2
cc per minute = lbs/hour x 10.2
-----
Convert cfm to Estimated Injector Size: (CFM * 0.44298) / No. of Cylinders = Estimated Injector Size
-----
HP supporté par injecteur: HP= (lbs/hr) x 2.04
-----
If these injectors produce 500cc @ 100% duty cycle, then sticking to a safe 75% duty cycle, 500cc at 75% duty is about 375 cc/min. At 375 cc the injector is good for about 85 hp each. 85x4=340 hp
-----
BHP = Maximum Brake Horsepower
BSFC = Brake Specific Fuel Consumption at peak horsepower
WHP = Wheel Horsepower
MAF = Mass Air FLow sensor
CAS = Cam Angle Sensor
ISC = Idle Speed Controler
BOV = Blow off Valve
-----


edit: en passant je savais pas trop ou posté ca, donc je l'ai mit dans How To, a vous de jugez ou ca devrais aller..?
