An incerase of pressure of one atmosphere, causes a reduction of [tex]49*10^-^6m^3[/tex] in a volume of [tex]1m^3[/tex] Give the value of the bulk-modulus of water. Calculate the denisty of the water of a lake, at a depth of 200 metres, assuming that the density of water is [tex]1000kgm^-^3[/tex] at the surface.
-----------------
Calculating the bulk modulus was pretty easy, gives a value of [tex]2.04*10^9Nm^-^2[/tex], but i don't really know how to relate this to a change in the denisty over a given depth... seems like an integration over a rate of change with density, but the question can't involve doing that. confused.. :\ help appreciated.
