Problem 3 The density of seawater at a free surface where the pressure is 98 kPa is approximately 1030 kg/m². Taking the bulk modulus of clasticity of seawater to be 2.34

10 N/m and expressing variation of pressure with depth as dp = pgdz determine the density and pressure at a depth of 2500 m. Disregard the effect of temperature. Recall that: (i) The bulk module of elasticity is defined as: E,- (ii) Density is not assumed as constant in this problem. dp dp
