    Design of vibratory equipment

    Hi guys, I'm starting to work with foundry equipment and I need to validate some information about a Shakeout (sand reclamation in the foundry, basically a heavy vibratory screen). I'm studying a lot but I guess I'm missing some points to verify if my drive is ok for the equipment, could you...

    Required area for drop pressure

    I did it now, considering 3 orifices in series the mach number in some situation are up to 0,7, so one problem solved, like you said, smaller orifice in the first device and big in the last, but the issue here (not exactly a huge problem), is that I have to define some pressure drop I want in...

    Required area for drop pressure

    My mistake, I've said "I have to maintain a branch of the pipe pressurized to simulate a combustion chamber before the compressor", the right word is AFTER the compressor. I have to keep the compressor outlet pressurized to be able to properly read the data from the instruments. This is a...

    Required area for drop pressure

    Rputvin, this project is for a laboratory where we are going to test prototypes of compressors (from gas turbines), only the compressors. So if I'm testing a compressor which has 8 bara in the exhaust, I have to maintain a branch of the pipe pressurized to simulate a combustion chamber before...

    Required area for drop pressure

    LittleInch, sorry about the last post. I misunderstood you, just now I realize you were walking about the flow velocity at the orifice and not at the pipe before the valve. The mach number there would be over 2 in some conditions from the table in the previous post. But even with that mach...

    Required area for drop pressure

    LittleInch, thanks for your reply, I just have a few comments: Below are some examples of compressors with real operation conditions. The maximum mach number will be at 0,13, so it wont be in a critical condition (if i'm not mistaken). ** in each 3 lines you can see the maximum, average and...

    Required area for drop pressure

    Good morning. I need to create a device (or valve) to reduce de pressure in the exhaust pipe of a compressor, from pressures between 1,1 and 10 bara to atmospheric pressure, so I need to create a range of drop pressure in some device that I could ajust the area. The device is simple, with 2...
