The drag force Fp on a smooth sphere falling in water depends on
the sphere speed V, the sphere density P. the density p and dynamic
viscosity of water, the sphere diameter Dand the gravitational
acceleration g. Using dimensional analysis with p. V and D as
repeating variables, determine suitable dimensionless groups to
obtain a reneral relationship between the drag force and the other
variables. If the same sphere were to fall through air, determine
the ratio of the drag...

Perform a dimensional analysis to obtain an equation for rising air bubble velocity, v. What variables would v depend on; i.e. what variables would you include in your analysis? Assume that v is a function of d (air bubble diameter). pw (density of water), g (gravitational acceleration), and uw (viscosity of water), and perform the dimensional analysis. How many dimensionless groups do you get (and why)? Look up the defintion of Reynolds number... Is Reynolds number of the dimensionless groups...

2) Falling Drops Imagine a solid sphere of diameter, d, falling through the air. After its release, the sphere accelerates until it reaches its terminal velocity. The terminal velocity is obtained when the drag force due to air friction, Fa, balances the weight of the sphere, W. The weight of the sphere is simply its...
