Calculate theoretical static pressure drop in moving fluid

  1. Nov 9, 2016 #1
    Hi folks,

    I have a pressure sensor working with arduino to measure depth. I want to calculate what I should see as a change in pressure if I move the tube horizontally under the surface of the water, keeping the tube opening parallel to the flow.

    I have calculated the dynamic pressure but need to calculate the total pressure to take a difference.

    Thank you!

    I can maybe turn the tube 90 deg into the flow and then measure that pressure?

    Could you provide a picture, perhaps? The shape of the tube and how the pressure transducer is related to it is not clear to me.
