Question: The average ocean depth is (2 mathrm{~km}). Compute the pressure at this point. Assume a constant density. The change in density of water with pressure
The average ocean depth is \(2 \mathrm{~km}\). Compute the pressure at this point. Assume a constant density.
The change in density of water with pressure is small, and can be represented using the bulk modulus \(K\) defined by the following equation:
\[K=ho\left(\frac{\partial P}{\partial ho}\right)_{T}\]
Recalculate the pressure now using the density variation. \(K \approx 2.2 \times 10^{9} \mathrm{~Pa}\) for water.
