Asubmarine 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
