After refreshing your theory and equipment knowledge, Please note the experiment availability as in table below. This experiment is AVAILABLE ON WED/THUR/FRI.
- Go to the RT tab and click "Click here to start experiment" in the variable panel.
- Click the "Start" button
- Click the "Pitot calibration" button
- Wait till the "Pitot position" in the station status to reach 40mm. only then the "Set air Velocity" slider will be activated.
- Start the tunnel by setting a velocity of 15m/s on the "Set air Velocity" slider (user can set the air velocity only one time)
- Adjust the "Set pitot position" slider to vertically traverse the pitot probe into and out of the wake region.
- Move the slider to 30mm. Wait for some time until the graph is plotted. Then move to the next position (20, 10... to -40mm) using the "set pitot position" slider.
- Click the "Stop" button to stop the experiment.
- Click the "Export" to export the velocity profile readings for post processing.
- Estimate the Drag from the momentum and velocity deficit behind the model as compared to freestream.
