AFF018 Losses in a Pipe System
pressure losses in the piping system
pressure measurement without interaction via annular chambers
transparent measuring objects for determining flow rate
Pressure losses occur during the flow of real fluids due to friction and turbulence(vortices). Pressure losses in pipes, piping elements, fittings and measuring instruments (e.g. flow meter, velocity meter) cause pressure losses and must therefore be taken into account when designing piping systems.
AFF018 allows to study the pressure losses in pipes, piping elements and shutoff devices. In addition, the differential pressure method is presented for measuring the flow rate.
The experimental unit contains six different pipe sections capable of being shut off individually. The pipe sections are equipped with piping elements such as bends, elbows and branches. In one pipe section, different shutoff devices and measuring objects are installed to determine the flow rate. The measuring
objects are made of transparent material and provide excellent insight into the inner structure. The pressure measuring points in the piping system are designed as annular chambers. This creates a largely interferencefree pressure measurement.
The experiments measure the pressure losses in pipes and piping elements,such as branches and bends. The opening characteristic of the shutoff devices are also recorded. The pressures are measured with tube manometers.
The experimental unit is positioned easily and securely on the work surface of the AFF018 base module. The water is supplied and the flow rate measured by AFF018. Alternatively, the experimental unit can be operated by the laboratory supply.
