    Reducing Water Pressure (Pipe sizing)

    I agree and this is exactly why I think it is unnecessary, but I need a good concise way to explain it to the team so that they also agree. I think it should be fine for us to drain staright from the filter to the facilities line without making any changes. It is simply a gravity fed drain line...

    Reducing Water Pressure (Pipe sizing)

    What if we just used an orifice plate? I still don't think any of this is necessary as there is no way that our 2L of 55psi is going to pressurize the open drain line but some people require extra assurance.

    Reducing Water Pressure (Pipe sizing)

    I have a problem at work and unfortunately it has been too long since I have been in a class room for me to reason this one out, never did like fulid mechanics much :). We have filter that is pressurized to approximately 55 psi. Once ever 12min or so this filter purges a volume of ~2L that...

    Tennis Ball Cannon Pressure & Exit Velocity

    Unfortunately I do not have a working model built yet, and wont for quite some time. Am I to believe there is not such equation in existence? I highly doubt that. I've seen a couple somewhat complicated differential equations that were used to arrive at the result I'm looking for but I cant say...

    Tennis Ball Cannon Pressure & Exit Velocity

    Yes this is far from an idealized situation and I figured I would take these things along with drag and friction into account when I actually have a working model to test varying pressures/distances with but for the time being I'm just looking for an expression to analytically determine the...

    Tennis Ball Cannon Pressure & Exit Velocity

    I'm designing a tennis ball launcher using compressed air that will hopefully be able to hit a target at some distance away. We wont know the exact distance until the day of the competition, but I was curious if there was some relatively simple equation relating the pressure of the compressed...
