  • Estimate the pressure deep inside the sea at a depth h below the surface. Assume that the density fo water is rho_(0) at sea level and its bulk modulus is B. P_(0) is the atmosphere pressure at sea level P is the pressure at depth 'h'

    A
    `P = P_(0) - B In (1 - (rho_(0)gh)/(B))`
    B
    `P = P_(0) + B In (1 - (rho_(0)gh)/(B))`
