    WEIGHT ESTIMATION ON SURFACES SUBMERGED IN BULK MATERIAL

    I now work in an industry where I am asked to design storage bins for food products and by products, etc. I often encounter a situation where I have to add a part in these bins that is going to have to support the weight of the product on top. A good example is a "turkey roost" which serves to...

    Flow through a perforated drum

    Thanks for the reply. I have uploaded a diagram of what I am working on. It is a screw chiller for olives. The idea is that the cold water comes in from a manifold in the bottom. The water flows through the outer shell into the perforated drum. Water dams prevent the water from short circuiting...

    Flow through a perforated drum

    Does anyone of a suggestion on how to estimate the flow of water through a perforated screen? I have a slowly rotating drum (1.2 rpm) 30" in diameter. I want to know how much water I can flow through it from the inside out. I will be pumping into it but it will drain by gravity flow. Any help...

    Fixed Lifting Frame

    Thanks for the quick reply. The setup is two A-frames supporting a horizontal beam. At the center of the beam is a fixed attachment for a hoist to connect to. The bottom of the A-frames are welded to steel beams that span a pit of water. I have a copy of BTH but I didn't think it would apply...

    Fixed Lifting Frame

    Could anyone point me to the design and/or OSHA requirements for a lifting frame? It is a gantry design made of stainless tube steel. It has one purpose and that is to lift a hinged section of conveyor out of the water for inspection. There are no trollies on this frame, just a fixed lifting...

    Soil Extraction Tank

    I am employed by a company that is producing a tank to be used to remove mud from water in food processing plants in areas where they wash the product after it comes from the cellar or field. The tank capacity is around 1700 gallons. The concept is that the bottom of the tank is conical and has...

    Rigging with a hook through a hole in a plate

    BAretired, thanks for the reply. The bolt through the plate situation would be similar to using a shackle instead of a hook. Since the hook is curved, it will only contact the hole at two point at either end of the hole. I normally use a safety factor of 5 for lifting applications. I think what...

    Rigging with a hook through a hole in a plate

    Thanks for the speedy reply Ron! Do you have any suggestions on how to design this connection type? Do you just assume that the hole is going to deform to the required geometry and then size the pin and plate thickness based on shear?

    Rigging with a hook through a hole in a plate

    I have a lifting application that I am helping with. I have been taught that in general it is bad practice to rig something using a hook in a hole drilled through a plate. This is due to the large contact stresses at the edges of the hole. A better alternative is using a shackle so that you have...

    Heat Exchanger Performance Testing

    Mr. Harding, Thanks for your reply. I looked up your company and sent you an email with the information you asked for.

    Heat Exchanger Performance Testing

    Thanks for the information. I will definitely check out the research center. Yes, you've described the test setup correctly. We attempted our own crude setup inside a large sink, but it was difficult to maintain a constant flow, inlet temp, and ambient water temp.

    Heat Exchanger Performance Testing

    Does anybody know of a facility that can performance test a heat exchanger? The heat exchanger type is basically a tube bundle between two heads that is submerged in water for cooling hydraulic fluid. It is not a shell and tube heat exchanger. I would like to have the heat exchanger tested at...

    Application of Self-Locking Patch

    Thanks for all the help. It looks like the ND Industries products were closer to what I was looking for than what I thought. I appreciate the input.

    Application of Self-Locking Patch

    Thanks MintJulep. I had looked at this site before. I don't think they sell a product to make patches. I believe they will apply the patch for you or sell you a fastener with the patch already applied. The user applied products are compounds similar to Loctite products. What I am looking for is...
