Example:
* Theoretic peak values depend in practice on local circumstances and can result in lower values.
Local circumstances:
4 bar of pressure, 1” water line (210 l/min)
Question:
How many cattle bowls can be connected in addition?
Calculation:
210 l/min : 12 l/min = 17,5 pieces
17,5 pieces x 2 (
empirieal values
) = 35 pieces
Answer:
35 pieces of cattle drinking bowls can be connected.

Water flow quantity depends on the following conditions:
Water pressure, length of pipes and cross sectional area as well as the quantity of reduction
pieces and curves.
Experimental values
, based on field test, revealed that not all the drinking bowls are actionned at
the same time. This way the result has to be multiplied with
factor two.
Technical data:
two separate residual current devices (RCD) two-pole
30 mA and four-pole 30 mA.
A damaged heating or pump can cause that the residual current circuit breaker triggers and the
heating unit and the pump are out of function. This leads that the water supply line risks to
freeze due to a cold outside temperature.
Special and corresponding steps have to be taken at the spot by the user to protect it
against freezing: e.g. frost protection heating cables, warning system, etc.
