The density of seawater at a free surface where the pressure is 98 kPa is approximately 1030 kg/m³. Taking the bulk modulus of elasticity of seawater to be 2.34 x 10⁹ N/m2 and expressing the variation of pressure with depth z as dP =rhog dz determine the density and pressure at a depth of 2500 m. Disregard the effect of temperature.
