Tips for correct watercourse calculation
• Use the pump performance curve to iden-
tify the required pump capacity (page 246).
To deliver the desired water quantity from
the pump to the source of the watercourse,
minimum hose diameters are required, e.g.
to 20 l /min = 25mm (1
")
or from 50 l /min
38mm (
1
½")
etc.
• In addition, it is important for the water-
course to pay attention to the pressure loss
of the water supply line. Generally this is
considered with 0.4 mWc. Consequently, for
displacement of greater quantities of water
it is necessary to use a more powerful filter
& watercourse pump. Larger water quanti-
ties increase pipe friction loss, and a higher
capacity pump is required.
Here is a rule of thumb for determining the
right pump for a watercourse:
Width of watercourse in cm x 1.5 l/min. =
capacity l/min.
