Differential Pressure Patch

Mainly used to test aerodynamic properties. 
Printed in ASA 0.1 layer height.

Uses 1,2 mm tube. 0,2 mm wall thickness, 0,8 mm hole i.e. inner diameter. Glued to 3D print with super glue for model building.

Can be used in conjunction with a Pitot tube and an analogue or digital differential pressure gauge/ sensor. 

A simple introduction to how it can be used to measure aerodynamic properties can be found in the video “Measuring aerodynamic pressures on the road or track” by Julian Edgar.
