This is what Ugarik said regarding water resistance:
"The force in newtons is calculated as F = 0.5*A*c*p*v^2, where
A - cross sectional area
c - drag coefficient
p - water density
v - velocity
This is only the pressure term, it should be used if the speed is much higher than the critical velocity.
You should use a different formula if the speed is low, but I don't know it"
So use this when calculating water calcs
