This module consists of a smooth rectangular bend with ten static tapping points on both the inner and outer curved walls, plus a further nine along the radius. Each one of the tapping points has a flexible tube with quick-release connector for connection to the AF10a Multi-tube Manometer (ancillary).
When air passes through the bend it creates areas of high and low pressure. The resulting pressure plots on the multi-tube manometer are highly visual which enhances student understanding. The readings allow the students to plot the pressure profile and calculate a value for the loss coefficient (K).
Learning outcomes
- Pressure distribution along the curved inner and outer walls.
- Radial pressure distribution and comparison with that predicted assuming free vortex velocity distribution.
- Calculation of loss coefficient (K)
