Compressible Flow Unit

Compressible Flow Unit

Technical Specification

FEATURES:
Investigate flow of compressible fluids
Subsonic and transonic air flow
Variable speed on the radial fan for adjusting the mass flow rate
Pressure losses in subsonic flow in pipe elbows and various pipe sections
Pressure curve at subsonic and transonic nozzle flow
Minimized turbulence by drawing in air and optimum arrangement of the measuring objects
Transparent measuring objects with connectors for pressure measurement provide insight into the internal structure
Measuring nozzle for determining the mass flow rate
Orifice for determining volumetric flow rate by differential pressure measurement
Record fan characteristic curve using a throttle valve
Digital displays for pressures, velocity and speed
