    Discharge Structure

    I'm involved in a project where we will be piping about 6000 GPM of water into an existing drainage ditch. The ditch is on BLM land and I believe the project may fall under the jurisdiction of the US Army Corps of Engineers, and they will review the design. The existing ditch is about 15 feet...

    MEASURING TWO PHASE FLOW

    Ilan, As a senior engineer, you just delegate the task of designing and implementing a two-phase flow meter to Reuven. I guarantee it will get done, and very interestingly. I like Kevin's approach. If you can do careful flow tests on the wells, with James tubes and weir boxes, you can...
