Need maths, water psf formula or conversion

[Science Abuse]

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?

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

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.

Would airs ability to compress skew that in any way? Seing "big noise" from explosions is an extreme example.

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.

"Ping"?

gniP <-- the sound wave comes back inverted.
