The graphs refer to the filling of a 10-litre tank and show the ratio of outlet to inlet pressure (= p2:p1) as a function of time (sec).
The graphs are valid for any inlet pressure between 2 and 10 bar.
The following formula can be used to calculate the time t (sec) required to switch from pressure ratio 1 to pressure ratio 2 in a tank of volume V (litres):
t = V (t2 – t1)
10
where t1 and t2 are the times shown on the x-axis, corresponding to ratios 1 and 2.
E.g.
1 = 0.4 = >
t1 = 2.5 sec
2 = 1.2 = >
t2 = 10 sec
The time required to switch from 1 to 2 with a 25-litre tank is:
t = 25 (10 –2.5) sec = 18.75 sec
