A research submersible vessel landed on Planet “W” and dived into its “ocean" of liquid ammonia to a depth of 13,526 feet. The average density of this fluid is 0.6821 g/cm². The gravitational acceleration on this planet is 11.6 m/s2. The enthalpy of vaporization and normal boiling point of liquid ammonia is 23.30 KJ/mole and -33.35°C, respectively. (1 m= 1.0936 yd)

(a) Calculate the hydrostatic pressure exerted on the vessel, in psi (use Properties of Liquid pdf)

(b) Calculate the boiling point, in degrees Celsius, of the liquid ammonia at this depth.
