I have made a pitot tube that I am using to measure the velocity of air in a pipe. First, I placed the probe into the pipe such that the hole in the probe was parallel to the flow to obtain static pressure. It did this successfully and I proved this using a piezometer. However, I then turned the tube such that the hole was normal to the flow to obtain stagnation pressure, but I am getting the same readings as I did for measuring static pressure. I know that since my flow is moving the stagnation pressure should be higher. Any suggestions as to why this is happening? I have attached a basic 3d model of what my probe looks like.
