    Volume of Horizontal Cylindrical Tank at angle

    Other than very basic derivitives everything in calculus is high level to me.

    Volume of Horizontal Cylindrical Tank at angle

    Hello All. Hopefully this is the best place for this question. It did not seem applicable to other forums. The question I have is I have a horizontal configured storage tank with capsule ends that is set on an angle for drainage. I need to know what the volume of this tank is at any height the...

    Horizontal stoarage tank saddle shroud

    EngAddict, do you know of any manufactures? I've been looking but have not found anything yet. I'm probably not using the right search term in google.

    Horizontal stoarage tank saddle shroud

    IFR and EngAddict. That was my first thought was some sort of flexible rubber skirt around it. Just was not sure what type of material and the best way to attach it.

    Horizontal stoarage tank saddle shroud

    The coefficient of friction would be too high with that size of PTFE pad. As the pressure increass the friction decrease. Sounds counter intuitive but that is the explanation that I got from the engineering firm who designed the pads. Even if we did have the same size pad as saddle I would...

    Horizontal stoarage tank saddle shroud

    Raising that high will still not prevent steam or water to get under the saddle plate. Also, that is not an option as the architectural design of the room will not allow it.

    Storage tank saddle bearing shroud

    jtseng123, it is a horizontal tank, not a vessel technically. This will not be pressure rated or air tight. I've moved the post here >http://www.eng-tips.com/viewthread.cfm?qid=329495 as this seems more appropriate for that forum. Did not see that on the list of forums when I posted it here...

    Horizontal stoarage tank saddle shroud

    My question is that I have a horizontal storage tank with one floating saddle on teflon pads. These tanks have a high cyclical load from thermal expansion so it will need to allow some flex in it. This will be in a pharmaceutical clean room with a lot of water and steam. What I need help with is...

    Storage tank saddle bearing shroud

    My question is that I have a horizontal liquid storage tank with one floating saddle on teflon pads. These tanks have a high cyclical long from thermal expansion so it will need to allow some flex in it. This will be in a pharmaceutical clean room with a lot of water and steam. What I need help...

    Steam venting.

    I have an application where we use hot water and steam to sanitize storage tanks. Currently the tanks are vented inside of the room but I want to use some sort of steam trap at the vent to capture the steam. Venting to outside is possible but in the summers the ambient exterior temperature can...

    Simulation desgin

    Yeah, the contoact pressure is what I want. The problem I am having is that I can't get the fixtures correct. The plate is floating on the "bearings" with the load pretty much uniformily distributed. All I want is to have a uniform load of 120,000 pounds distributed onto the three bearings. I've...

    Floating saddle base for water tank

    Thank you guys for all of your help on this. I think I've gotten my design and have found a supplier to make it for me. The company recommends that I have a minimum applied force of 75 psi on the pads during the expansion cycle though. Does this sound correct? Under these guidelines I will use...

    Simulation desgin

    I posted this in the wrong forum so I am going to put it on here. I am trying to determine the amount of stress that is occurring to a plate that is being supported by three bearings. I am not sure if my results are coming out correctly or not. The intent is to have the bearings fixed and a...

    I've also attached the assembly that if this helps you understand what I am working on.http://files.engineering.com/getfile.aspx?folder=c75d0ca9-383a-4949-8d6e-611a5874ab30&file=Bearing_Load_Study.zip

    Simulation Help

    I am new to working with the simulation program in Solidworks and hoping this is the right location to ask this question. I am trying to determine the amount of stress that is occurring to a plate that is being supported by three bearings. I am not sure if my results are coming out correctly or...

    Floating saddle base for water tank

    dhengr 1) The tanks have been designed for UBC seismec zone 3. (Just to clarify when you say A.B. do you mean attachment bolt?) 2) The saddle plate does account for the slope. The slope will be compensated with the fitment of the saddle to tank interface. I will have to confirm the design with...

    Floating saddle base for water tank

    I've attached a more detailed drawing of my application. From my research and doing a little math I think my best option is to us a polish stainless upper plate attached to the saddle and a PTFE bonded to a steel plate on the bottom. I am think that using two smaller pads in lieu of one larger...

    Floating saddle base for water tank

    The floating saddle has slotted holes so it can slide.

    Floating saddle base for water tank

    I've attached a very crude hand sketch of the tank with major dimensions. The tanks have been designed and are being built as we speak so no changes can be made to them. I just started working on this project a few days ago so I was not involved with the design or these considerations...

    Floating saddle base for water tank

    I need to design a "floating" base for a 42,000 litre, round, horizontal stainless steel water storage tank. Total weight will be 120,000 lb full and a tad under 20,000 lb empty. One saddle will be fixed but the other saddle will be "floating" to compensate for thermal expansion. Steam is used...
