-Combustion Formules-
Q=mcombPCI
mcomb=Q/PCI
PCI=Q/mcomb
Q'=mcombPCS
mcomb=Q'/PCS
PCS=Q'/mcomb
Q'=Q+meauLv
Q=E/n
E=Qn
P=m/V
V=m/P
m=VP
-Significations-
Q: l'energie thermique 
fournit par la combustion 
en J
mcomb: masse combustible 
en Kg
m: masse en Kg
PCI: pouvoir calorifique 
inferieur en J.Kg
Q': l'energie thermique 
fournit par la combustion
en J
PCS: pouvoir calorifique 
superieur en J.Kg
meau: la masse d'eau produite
par la combustion en Kg
Lv=2.2510^6 J.Kg 
Lv: energie massique de
vaporisation de l'eau en J.Kg
n: rendement 
(chiffre 
decimale pas % ex: 0.95)
E:en J
P=masse volumique
V=volume en L
-Rendement-
n=E/Q
Exemple de rendement n:
n=Qeau+Qcanette/Qethanol
-Lecon et TP-
1Wh=3600J 1KWh=3 600 000J
1m^3 d'eau= 1000L
Relation systeme isolé: 
  Somme Q1+Q2+Q3=0
Afin d'ameliorer le rendement
il 
faut isoler les corps
