Exemple :
V = 1,5 PI (0,5m)
1
V = 5 PI (1,5m)
2
V = V + V = 1,5PI (0,5m) + 5PI (1,5m) = 6,5 PI (2m)
T 1 2
H = 1 PI (0,3m)
1
H = 1 PI (0,3m)
2
H = 10,75 PI (3,3m)
3
H = H + H + H = 1PI (0,3m) + 1PI (0,3m) + 10,75PI (3,3m) = 12,75PI (3,9m)
R 1 2 3
H = 0,03 (quatre coudes 90° + un coude 45° - 90°)
O
= 0,03 (360° + 45° - 90°) = 6,75 PI (2,1m)
H = H + H = 12,75PI (3,9m) + 6,75PI (2,1m) = 19,5PI (5,9m)
T R O
H + V = 19,5 PI (5,9m) + 6,5 PI (2m) = 26 PI (7,9m)
T T
Formule 1 :
H < 3 V
T T
3 V = 3PI (0,9m) x 6,5PI (2m) = 19,5PI (5,9m)
T
19,5 PI (5,9m) = 19,5 PI (5,9m)
Formule 2 :
H + V < 40 PI (12,2m)
T T
26 PI (7,9m) < 40 PI (12,2m)
Puisque les deux formules sont respectées, cette configuration d'évacuation est acceptable.
