Figuring the flow rate and pressure of an air horn
First off let me state I'm out of my wheelhouse with this and it's been many years since high school physics. (I had a soft science major in college). That said, I'm working on a project and I keep getting the same question. What flow rate and psi do you require? Essentially I need to mimic the flow rate and psi of that created by a compressed air horn. So how much air, and what psi are needed to make the horn blow? I can easily get figures for air horns with mechanical compressors, but it seems much more difficult to get this information for air in a can. I imagine that there are slight variations between horns but I'm talking about your basic signal air horn that you would buy from West Marine.
