For an individual project I'm working on, I've been trying to work out what the tensile strength would need to be for a spherical container to hold a given volume and density of liquid. The specific values are given below, but a general formula would be useful too. Mass of liquid: 2 660 000kg Density of liquid: 1000kg/m^3 Hence, volume of liquid: 2 660m^3 Hence, diameter of container: 17.2m And surface area: 929.41m^2 Temperature of liquid: 36.5°C Force exerted on container per m^2: ??? The container is exactly large enough to contain the liquid, and no larger. I'm not sure what equations to use here. If any further information is needed to work out the answer, please let me know what it might be.
