5. (Randall 6-16): A small submarine that displaces a volume of 15 m³ is submerged in seawater with a salinity of 34 ppt and a temperature of 16°C. The water density is given approximately by the equation p = 1001.52 – 9.10 x 10-3 T2 – 4.09 x 10-3 TS + 8.24 x 10-1 S kg/m3 Determine the weight of the submarine when T is in degrees Celsius and S is in parts per thousand.
