FLOW CHARTS

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
