A solid sphere having a diameter d and specific weight γs is immersed in a liquid having a specific weight γf (γf > γs) and then released. It is desired to use a model system to determine the maximum height, h, above the liquid surface that the sphere will rise upon release from a depth H. It can be assumed that the important liquid properties are the density, γf/g, specific weight, γf, and viscosity, μf Establish the model design conditions and the prediction equation, and determine whether the same liquid can be used in both the model and prototype systems.
