    Reaction force to a flat and curved surface study

    hi, let's assume that these both are valves, these have pneumatic pressure applied onto the surface. I have pressure values inside the tank. As such the tank is big, and there is very less variation of pressure inside the tank, I am assuming constant pressure which is acting on the surface. As...

    Reaction force to a flat and curved surface study

    @rb1957, the arrows in both the pics are of force direction. I forgot to mention the force. And yes, the pressure will act normal to the face. The ball half under water, pressurized from below (so it will not be under hydrostatic pressure, which will result into different pressure values on the...

    Reaction force to a flat and curved surface study

    thank you for your reply folks, that is what I am trying to understand. As such the pressure will be from the fluid beneath them and will be applying same pressure (as per pascal's law). If instead of the curved surface, if we take a ball of the same diameter, will the reaction force be the same...

    Reaction force to a flat and curved surface study

    Hello Engineers, I have two different geometries, where i know the value of pressure. I would like to know the reaction force on both the scenarios. Applying the same pressure on both the geometries, there is not at all difference in reaction force in vertical direction (even though the surface...

    Pressure drop in a plate heat exchanger

    Okay, so i just need to consider that pressure drop as for entire exchanger, right? Need to evaluate pressure drop at inlet and outlet too though which will add up for entire exchanger.

    Pressure drop in a plate heat exchanger

    Hi TugboatEng, thanks for your reply. How can a pressure drop for single plate be equivalent to pressure drop across exchanger? I have pd for a plate. I need to evaluate for exchanger which has N number of plates.

    Pressure drop in a plate heat exchanger

    Hi Rputvin, thank you for your reply. The pressure drop I have mentioned is from two plates joined and the fluid passing between them. Other plates are not considered, and also only one fluid media is considered which is passing. Yes there will be N parallel plates and two different media (one...

    Pressure drop in a plate heat exchanger

    Hello Engineers, I have a pressure drop for an individual plate. Now i would like to evaluate the pressure drop in a PHE where there are N number of plates. How would i do it? Is there any approach for that? Thanks, jmex https://about.me/jdmech

    Lame question on tank analysis

    Thank you for your replies. I know that hydrostatic pressure will vary from surface to deepest point. That's why there is an option of hydrostatic pressure in ansys which is different from pressure. Now my question is, am i suppose to apply atmospheric pressure(14.6959 Psi) to all surface inside...

    Lame question on tank analysis

    Hello all, I am trying to understand the inputs here. Let's suppose I have a water tank at home which is made of plastic. It is filled with water. So I am confused with the inputs. At first when I gave only hydrostatic pressure, the tank was safe. But when I added atmospheric pressure by...

    ASTM A36 chemical requirement

    Hello, I have a doubt regarding ASTM A36 Grade. Scrolling down to chemical requirements, Manganese in plates and bars of below 3/4" are 0%. What if it contain manganese? Or why standard don't have manganese included in table for particular size? Thank you https://about.me/jdmech...

    Aluminum Pressure Rating Class Standard

    thanks for the replies. Found ASME B31.3 stating that Flanges shall meet the dimensional and tolerance requirements of ASME B16.5 under Appendix L.[thumbsup2] https://about.me/jdmech

    Aluminum Pressure Rating Class Standard

    Hello, I use ASME B16.5 for flange dimensions for SS and CS materials. Is this standard applicable to Aluminum material too? Which all materials are covered in this standard? Thanks https://about.me/jdmech
