Q6. The force acting normal to the centerline plane of a rudder is given by the expression:

Fn = 15.5 A v2 α newtons

Where, A = Rudder area (m2)

v = Ship speed (m/s)

α = Rudder helm angle (degrees)

A ship travelling at a speed of 20 knots has a rudder configuration as shown in Fig Q4. The center of effort for areas A1 and A2 are 32% of the width from their respective leading edges. The rudder angle is limited to 35º from the ship's centerline.

Calculate EACH of the following:

(a) The diameter of the rudder stock required for a maximum allowable stress of 77 MN/m2;

(b) The drag component of the rudder force when the rudder is put hard over at full speed.

Q7. (a) The residuary resistance of a 1/25 scale model of a ship is 6.35 N when tested at 1.543 m/s in fresh water of density 1000 kg/m3. The frictional resistance of the ship at 12 knots in sea water of density 1025 kg/m3 is 145 kN. Frictional resistance can be assumed to vary with speed to the power 1.825. Calculate the effective power (naked) for the ship at the speed corresponding to the model test.

(b) The following additional data apply to the ship operating in service at the corresponding speed calculated in Q6 (a) with a propeller having a pitch of 4.6 m.

Appendage and weather allowance = 22%

Quasi-propulsive coefficient (QPC) = 0.7

Propeller speed = 1.75 rev/s

Taylor wake fraction = 0.32

Propeller thrust = 565 kN

Calculate EACH of the following:

(i) The torque delivered to the propeller; (ii) The propeller efficiency; (iii) The real slip ratio.

Q8. A ship consumes an average of 70 tonne of fuel per day on main engines at a speed of 17 knots. The fuel consumption for auxiliary purposes is 8 tonne per day. When 800 nautical miles from port it is found that only 140 tonne of fuel remains on board and this will be insufficient to reach port at the normal speed. Determine, using a graphical solution, the speed at which the ship should travel to complete the voyage with 20 tonne of fuel remaining.

Q9. At a draught of 1.0 m in sea water of density 1025 kg/M3 the displacement of a ship is 900 tonne and the height of the centre of buoyancy above the keel (KB) is O.6m. Values of tonne per centimetre immersion (TPC) in sea water for a range of draughts are given in Table Q1.

(a) Calculate EACH of the following for a draught of 6. Om in sea water:

(î) the displacement; (ii) the height of the centre of buoyancy above the keel (KB).

(b) At a draught of 6.0 m, the height of the longitudinal metacentre above the keel (KML) is 128m and the second moment of area of the waterplane about a transverse axis through midships is 996 728 m4. The centre of flotation is aft of midships.

Calculate the distance of the centre of flotation (LCF) from midships.

Q10. A ship of 10000 tonne displacement floats in sea water of density 1025 kg/m3 at a draught of 6m. A rectangular tank 10m long and 8m wide is partially full of oil fuel of density 900 kg/m3. In this condition, the KG of the ship is 6.25m.

Other hydrostatic data for the above condition are:

Centre of buoyancy above the keel (KB) = 3.325m

Transverse metacentre above the centre of buoyancy (BM) = 4.865m

Tonnes per centimetre immersion (TPC) = 20.5

Calculate the change in effective metacentric height when a rectangular tank 12m long, 10m wide and 6m deep, with its base 1 m above the keel, is filled to a depth of 5m with sea water ballast.

NOTE: Assume the ship to be wa11sided over the affected range of draught
