Calculation

Easy approximation calculation

We assume that...

 The inside of the hull is jam-packed with E.coli. The lower surface of the hull is totally covered with E.coli. Individual thrusts do not interfere each other. 

The weight of the Titanic in water = 4.0 × 108 N Volume of the Titanic = 9.7 × 104 m3 Thrust by the total flagellum (thrust per one flagella = 0.29 pN)  2.5 × 103 N <li class="B">Buoyancy by the total gas vesicle  (buoyancy per one gas vesicle = fgas pN)  fgas × Vtitanic / VE.coli = fgas × 9.7 × 1022 N</li>

The Titanic floats when fgas is more than 4.1 × 10-3 pN !!

Further simplification It is assumed that the ship floats when filled with the same volume water as that of its underwater part.
