When water flows through a pipe system there are resistances
as a result of changes in direction, valves and fittings and pipe friction. The
flow resistances are directly dependent on the geometry of the pipe elements
and the number and type of fittings. In addition, the flow velocity plays a key
role in the occurrence of pressure losses. The unit can be used to investigate
and visualise the pressure distribution in a pipe system. The trainer enables
the examination by experiment of different influencing factors on the pressure
losses in real pipe systems. The relationship between pump characteristic and
system characteristic is studied in the experiment. The pipe elements used are
commercially standard components in heating and sanitary engineering. The clear
panel is mounted on a sturdy, movable frame.
