calculating force on object being lowered/dropped into water
Any info/resources on calculating the hydrodynamic force on an object when it hits the water surface with constant velocity?
cheers |

thanks simon,
both are good. trying to get good understanding at "tertiary level", so that i can then put it into a design equation at "secondary school level" :) haven't had a good read through either yet but i'm ok with submerged buoyancy, drag etc. it's the force acting on the object as it hits the water i need to understand better. out of interest - do you have drag force and drag coefficient for a square object? |

Not lying around no.
These things are not trivial to work out - especially as you'll get turbulent motion. It's usually easier just to do an experiment. |
