quick overview :
It is part of a series that allows experiments on the fundamentals of air flow. The software for data acquisition and visualisation makes the experiments especially clear and enables fast execution of experiments with reliable results.
The experimental unit includes a radial fan, which can be used to generate flow velocities up to 9m/s. An inlet contour on the intake side ensures a low-turbulence flow and thus a homogeneous velocity distribution in the measuring section. A throttle valve on the end of the pressure pipe can be used to adjust the air flow to allow the fan characteristic curve to be recorded. When used in conjunction with the power meter it is possible to determine the efficiency of the fan.
