If, on the other hand, a green spray lance is selected = 33 l/min + a standard spray lance = 17
l/min the maximum load on the line
b-c
= 33 l/min.
PRESSURE
DROP
Use of 50 m
∅
15 mm pipe will result in a pressure drop of:
9.3 bar
Maximum load on line
a-b
= 50 l/min.
Use of 40 m
∅
22 mm pipe will result in a pressure drop of:
2.0 bar
Maximum load on line
M-a
= 50 l/min.
Use of 70 m
∅
22 mm pipe will result in a pressure drop of:
3.2 bar
Total pressure drop
14.5 bar
The aggregate pressure drop on the three lines is less than
15 bar
and the dimension require-
ments have therefore been met.
Example 2
Branched system
Selection of spray lance: 2 green spray lances each of 33 l/min
2 blue spray lances each of 17 l/min
PRESSURE
Maximum load in each branch is 33 l/min
DROP
Use of
∅
15 mm pipe on e.g. the
a-a2
line
(20m) will result in a pressure drop of:
4.0 bar
Maximum load on line
b-c
= 66 l/min
Use of 30 m
∅
22 mm pipe will result in a pressure drop of:
2.5 bar
Maximum load on line
a-b + M-a
= 101 l/min
Use of 40 m
∅
22 mm pipe will result in a pressure drop of:
7.5 bar
Total pressure drop
14.0 bar
The aggregate pressure drop on the three lines is less than
15 bar
and the dimension require-
ments have therefore been met.
