4.1.1.3 Determining the compressed air and water requirements
Compressed air requirements
The compressed-air consumption of a system depends on the number of atomisers and is calculated
using the following formula:
Q
L
= n
D
* 60Nl/min
BS10
30Nl/min
BS5
Q
L
: Necessary air volume in Nl/min
n
D
: Number of devices
Related to the example and using the following values:
n
D
= 5
The result is an air volume of 300 l/min.
NOTE:
In order to ensure a trouble-free operation, the compressed-air system ought to deliver 1.2 times
the air volume that has been calculated.
Water requirements
The water requirements of a system depend on the number of atomiser and is calculated using
the following
formula:
Q
W
= n
D
x 10l/h
Q
W
: Necessary water in l/h
n
D
: number of devices
Related to the example and using the following values :
n
D
= 5
The result is a water volume of 50 l/h (110.5 lbs/h).
NOTE:
In order to ensure a trouble-free operation, the water system ought to deliver 1.2 times the
maximum water volume that has been calculated.
