Hello,
I am working on a Marine project that consists of a 5 foot diameter hollow sphere, ( a Buoy), that has quite a bit of instrumentation within, and protruding out , antennae, sensors, transmitters, etc. that communicate with both satellites and ground receivers. This sphere has a rather long fixed ballasted keel, with a 40 “ hollow ellipse attached, designed to hold lead pellet ballast, to control what is called the “Righting Moment”, and keep the sphere, with it’s protruding measuring, and transmitting instruments, as upright as possible in high winds and waves.
My question is, assuming that I know the density of the ballast material, how can I calculate the weight of the ballast, with Solidworks, that will nearly fill the football shaped ballast tank attached to the keel ?
Thank you,
Guido

Or create a sketch on a plane at the fill level, and extrude Up To Body. Depending on the shape, you may have to create a couple of features (or a mirror)
