I am currently doing a research project in the attenuation of pressure waves. With an focus on dealing with sonic booms the are generated from high speed train tunnels. my experiments involved pressurizing a cylinder then using a rapid release valve allowing the air to escape along a pipe. I having issues in my head determining between static and dynamic pressure and the readings i have taken are confusing me. Any advice would be appreciated.
The graphs posted below:
the 1st plot
the dashed red line is the pressure inside the vessel after the valve is opened.
the black line is the pressure history of the 1st transducer in the pipe the pipe line is the pressure transducer near the exit if pipe
other lines are pressure transducers attached to the vessel.
the second plot
the gauge and the transducers start at the same level as the transducers only detect a change in pressure and won't detect a static pressure
