Buckingham Pi Theorem
Sample questions
- What is the pressure within a soap bubble of given radius of curvature?
- What is the frequency of oscillation of a small water droplet suspended in air (like the kind you see coming out of astronauts’ straws in zero-gravity environments)?
- Sterl’s problem on thermodynamics of a relativistic gas (for homework).
- A photograph of an atomic explosion in New Mexico reveals that the radius of the shock wave is 150 meters at a time of 1.5 milliseconds after detonation. Estimate the energy released in the explosion in equivalent tons of TNT.
- An isothermal, non-rotating molecular cloud core that is in marginal hydrostatic equilibrium begins to collapse gravitationally. At what rate does mass accrete onto the young star at its center?
- Derive the maximum size of a falling raindrop.
