Chapter 1: Earth (Numericals Solution)

Stability 1 – Chapter 4 Solutions for Exercise 4: Some important terms – displacement; deadweight; form coefficient; reserve buoyancy; Tonnes per centimetre. Solution : Area of box shape vessel = (L x B)= 120m x 15mLight draft = 4m Light displacement = (u/w volume) x ( density)= (L x b x d )x (1.025)= (120…

SOLUTION: Given : L =16m , B = 15m, H = 6m, RD=0.7 =16x15x6 = 1440m3 We know that : Density = Mass /Volume0.78 =Mass/1440m3 Hence, Mass =1123.2 tonnes SOLUTION: Given: Diameter = 8m, Radius = (d/2)m=(8/2)m =4mHeight =10mMass = 400tRD =0.9 We know that: Volume of the cylindrical tank = π2h= 3.1416 x 4…

Solution : Volume of rectangular log = (L x b x h)= (8m x 2m x 2m)= 32m3 Weight = (U/W volume ) x (Density of displaced water)Weight   = (8 x 2 x1.6) x(1)= 25. 6t RD = (mass / volume)= 25.6 / 32= 0.8t/m3 . Solution : Volume of rectangular log = (L x B…

Solution :  Area of the flat keel plate = (10 x 2) = 20m2               Pressure = (depth x density) = (8 x 1.025) =  8.2t /m2                                 Thrust = (pressure x area)         …

Stability 1 – Chapter 5 Effect of Density Solutions > Exercise 5: Effect of density on draft and displacement – FWA ; DWA ; loadliness of ship. Solution: Displacement (W) = 16000 tTPC = 20 & SW draft = 8.0m We know that: Displacement when in SW = ( L X B x draft) x…
