A submarine is powered by a nuclear reactor that consists of the reactor coolant, steam generation and other support systems that supply steam to the engine room. The pressurized water reactor (PWR) uses 20-45% enriched uranium-235 fuel to produce 165 MW of power, driving two 26 MW steam turbines that generate electricity and drive the propeller shaft The submarine has a displacement of 19800 tons submerged, crew of 105, length of 185 m and width of 12 m. Calculate the speed of the submarine when surfaced and submerged in kn (knots) or km/h. a) Use the PWR data to determine amount of power generated & use shaft work correlation to calculate the submarine propulsion when surfaced & submerged b) The speed of the submarine must be realistic as the fastest submarine speed recorded is 32 kn. Show all necessary calculations c) Specify no of screws/blades from your calculation
