LittleInch, thanks for your reply. As far as pressure drops in the 1" line, the only losses are the friction through the pipe and fitting. If I find that there isn't enough head at the 2"/1" junction, how do I increase the head at that tee location?
Hoping for a little help. I have a system that will be using 1 pump that will pump to two branches. In this system, we’re pumping a total of 42gpm of water, 40 gpm flows through 2" SCH80 pipe to a scrubbing tower. There is a tee off of the 2" pipe that flows 2 gpm through 1" SCH80 pipe that goes...
Hello:
Looking for a little advice. We are a provider of municipal and institutional swimming pool filters. We have installations all over the world at various water parks, high schools and YMCA's. Occasionally, we get contacted from customers that have had the filters in service for only a few...
LittleInch, not being shy regarding the flowrate. I asked the client to provide. Still waiting for an answer. I was thinking about straightening vanes, but the perforated flow conditioner is a great idea. Thanks.
Bimr, filter runs are typically 6 hours.

Inside the filter is a nest of hundreds of tubes that hang down from an upper plate. Each tube is coated with a filter media. There is a baffle on the inside of the filter that intended to redirect the flow through the center of the filter theoretically spreading the flow move...
Hello:
A client is complaining that there is excessive turbulence inside a filter as the water enters the vessel and is asking what to do about it. Attached is a drawing they provided of the piping arrangement. My first observation was two things. It seems they are reducing the pipe size very...
Has anyone ever done any calculations to use a a rolled angle as a flange for bolting a head to a shell? This is not an ASME vessel and I’m just looking for a calculation method to be able to calculate the quantity and size of bolt holes and checking the thickness to use a rolled angle as a...
I'm looking for some help to determine the size and quantity of stainless steel bolts for a flanged joint as shown in the attachment. The flange is for joining the head and body of a non-code pressure filter. The head and body flanges are rolled leg out from 2"x2"x3/8" 304L stainless steel angle...
I'm needing to design a rectangular tank under hydrostatic pressure. I've been looking at procedures in "Design of Weldments" by Blogett, "PV Handbook", and a procedure I downloaded. The dimensions of my tank are 72"Hx72"Wx243"L made from A36 Carbon Steel.
Every procedure starts out by...

Thank you for you reply, it was very helpful. One question, If our goal is to maintain temperature, does the number of air changes needed come into play in determining the louver size?
The company I work for provides containerized water treatment equipment. The containers are standard sea boxes. Typically we install an exhaust fan in one wall of the container and an intake louver in an opposite wall of the container. I'm trying to find some guidelines for the following:

I'm attempting to create a Purchase Order form. The way I have started to setup the form, I have a Combo Box that has a list of our most popular vendors. I would like to have the user be able to select the vendor from the list and based on their selection, have the vendor's address, phone no...
Thank you all for your replies. Was really looking to see if there was a calculation that would determine how high the liquid level in the tank would rise at a known flowrate and a know exit pipe size.
The tank is atmospheric (open top) and used as a Coagulation/Flocculation tank in the water treatment process. True, what I called weirs I suppose are really baffles. Moving from left to right, Coagulant is added into the first chamber where there is a high speed mixer to disperse the chemical...
