Dtermination de G :
Daprs la descente de charge calcule auparavant, on a :
= 206 2 5.66 = 1165.96
Et () = 0.25 2500 5.66 = 3537.5 /
(6) = 0.85 0.4 2500 = 850 /
(3) = 0.8 0.4 2500 = 800 /
La charge dexploitation est :
= 400 2 5.66 = 2264
Do
= 1.35(1165.96 + 3537.5 + 850) + 1.5 2264 = 10893.175 /
Et
= 1.35(1165.96 + 3537.5 + 800) + 1.5 2264 = 10825.675 /
