1. A submarine is sent to a certain depth in the Atlantic Ocean to investigate lifeforms present in the layer. The density of seawater measured in the deep layer is 1040 kg/m3. The coefficient of compressibility of water in the deep layer is 2.45 GPa. Calculate the absolute pressure at this layer given that the ocean’s surface density is 1035 kg/m3 and the absolute pressure is Pa = 101.3 kPa.
