3.5.1 Head with total rate of flow
to other zones
In “30/130” versions using the second
and third zone kit, determine the head avai-
lable to the zones as shown in the following
example:
Rate of flow calculated for zone 1 = 350 l/h
Rate of flow calculated for zone 2 = 400 l/h
Rate of flow calculated for zone 3 = 400 l/h
To obtain head available to zone 1, add the
total rate of flow to the other zones (in this
case zones 2 and 3): 400 l/h + 400 l/h =
800 l/h.
As shown in the graph (fig. 18/a) at the
800 l/h curve, head at 350 l/h for zone 1
= 180 mbar.
The same procedure may be applied to
other zones to obtain:
Zone 2 = 350 l/h + 400 l/h = 750 l/h.
As shown in the graph at the 800 l/h
curve, head at 400 l/h = 160 mbar.
Zone 3 = 350 l/h + 400 l/h = 750 l/h.
As shown in the graph at the 800 l/y
curve (curve E), head at 400 l/h = 160
mbar.
3.5.2 Head available with the low
temperature kit
In “30/130” versions using the low tempe-
rature kit, residual available head on the
basis of rate of flow is represented in the
graph in fig. 18/b.
