COMPRESSIBLE FLOW STUDY BENCH Model FM 76
Sci-tech Compressible Flow Study Bench Model FM 76 experimental unit is used to investigate air flow in various ranges of velocity.
A radial fan with infinitely variable speed control draws in air from the environment. At the intake the air flow is accelerated in a measuring nozzle. Further down the measuring section the air flows through interchangeable measuring objects. Drawing in the air and the arrangement of the measuring objects on the intake side of the fan minimize turbulence when flowing into the measuring objects. All measuring objects are made of transparent material and provide excellent insight into the inner structure.
Pressure losses are studied in a pipe elbow, various pipe sections and a nozzle with sudden enlargement. The nozzle with gradual enlargement (de Laval nozzle) provides an introduction to the topic of sonic flow. The volumetric flow rate is measured in an orifice using a differential pressure manometer. The orifice is fitted with four interchangeable orifice disks for different measurement ranges. The fan’s characteristic curve can also be recorded by using a throttle valve.
The measured values for volumetric flow rate, pressure and speed are displayed digitally.

Item Description
Features
- Investigation of flow in compressible fluids
- Varied range of experiments for studying subsonic and sonic flow
- De Laval nozzle generates velocities up to Ma 1
Compressible fluids change their density due to pressure change in the flow. Flows with velocities less than Ma 0,3 are regarded as incompressible and the change in density is negligible. At higher velocities, the density has to be included in calculations. These conditions must be taken into consideration when designing e.g., turbo compressors, jets and fast planes.
