Principles of Air Flow Studies Apparatus Model FM 108

Sci-tech Principles of Air Flow Studies Apparatus Model FM 108 allows experiments on the fundamentals of air flow.

Item Description

Optional software for data acquisition and visualization 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.
Further accessories for additional experiments can be attached in the intake pipe: electronic total pressure sensor, pressure distribution on a cylinder and heat transfer at a cylinder in transverse flow. To study the friction losses, the intake pipe is replaced with pipe elements from (straight pipes, pipe bends and pipe angles). Measuring points along the measuring section allow temperature, pressure and velocity measurements to be taken. The flow rate is determined by means of the inlet contour and the pressure measurement. The measured values are transmitted directly to a PC via USB. The data acquisition software can be included optionally.

 wide range of accessories for basic experiments with air flow
