    Fluid Mixing

    Thanks for the reply LittleInch, I am reading Perry's Chemical Engineering Handbook on Fluid mixing and perforated tube mixing. It has very general information and I understand that each problem is unique but I am just looking for what people have done in the past or "rules of thumb" to try and...

    Fluid Mixing

    I am using a 2.5" diameter pipe with 60 3/16" holes and 24 feet long placed at the bottom of a 4200 gallon tank. Is there anyway to find what pump flow rate to use to achieve the correct velocity and turnover for effective mixing? The fluid is 25% Caustic solution.

    Perforated Pipe Question

    Can any of you suggest a proper way to gauge how much flow is desired to get good mixing? I have determined that I will replace the existing perforated pipe and install a new one. It will be 2.5" diameter pipe with 60 3/16" holes and 24 feet long. Currently with a 20 GPM pump I am getting a...

    Perforated Pipe Question

    The file provided is exactly the scenario I have. The literature and references showed the calculation needed to size the holes and how many is needed. but for your information: 1, Discharge 2, 4200 GAL 3, Caustic soda approx. 30% solution

    Perforated Pipe Question

    Thanks again for responding, I am unsure of the exact pressure drop I can afford but a rough estimate would be 7-10 psi. Also all fluid is discharged back into the tank, a control valve is in place for flow control but all fluid is routed back to the tank. The data I have so far is Pump: Max...

    Perforated Pipe Question

    Thanks for the info, I should make it clear as well that I am recirculating the fluid into itself. There is no gas or air used.

    Perforated Pipe Question

    Im looking to do some calculations on a pump hooked up to a perforated pipe in a tank. The reason is purely for recirculation and agitation. I cannot find any formulas or guides as to how many hole and what size is a safe range( or desirable range) for a given pump and tank size. Any help or...
