Science Abuse Posted June 29, 2007 Report Share Posted June 29, 2007 So, I've got a great formula that takes wind speed and gives you PSF (i.e. windload) at sea level. I need this for water at sea level also, or a conversion to plug into my existing formula to make it work. Anyone? Quote Link to comment Share on other sites More sharing options...
Science Abuse Posted June 29, 2007 Author Report Share Posted June 29, 2007 May have a lead; Density 1.2 KG/M^3 vs 998.536 kg/m^3 So, would that mean that freshwater is 832 times denser then ain, and therefor object moving through said water would have 832 time more drag....? hmmm Quote Link to comment Share on other sites More sharing options...
Akula Posted June 29, 2007 Report Share Posted June 29, 2007 The sound velocity in air is about 1000 fps, in sea-water it is 5000 fps (appx). Thus, as sound is concerned, it is 5 times more dense. Quote Link to comment Share on other sites More sharing options...

Akula Posted June 29, 2007 Report Share Posted June 29, 2007 certainly, but since I am only a navy trained expert in how sound travels in the water I wouldn't know how or why. I would think that compressed air would be denser and would allow for sound to travel faster however the less compressed air at the edge of the explosion would refract the sound waves.

Akula Posted July 2, 2007 Report Share Posted July 2, 2007 gniP <-- the sound wave comes back inverted. Quote Link to comment Share on other sites More sharing options...
