Question

(a) An open-topped rectangular metal boat containing sand as a ballast floats on water. The boat
has a width of 200 mm, a length of 800 mm, a height of 500 mm and a mass of 10 kg.
Determine the mass of sand (kg) required for the can to be immersed to a depth of 250 mm
in water. How should the sand be distributed in the floating boat? (Density of water 1000
kg/m³, density of sand 1600 kg/m³).
(b) A venturi meter, as shown in Figure Q5, is attached to a horizontal pipe through which oil
(relative density 0.9) is flowing. The tube narrows from a cross-sectional area A, of 0.5 m² to
a cross-sectional area A2 of 0.4 m². The difference in pressure between area 1 (A1 ) and
area 2 ( A2 ) is Ap = 2.5 x 10-2MN/m². Calculate the volumetric flow rate and the velocity of
the fluid as it passes through the two sections.

Bathyscaphes are capable of submerging to great depths in the ocean. What is the pressure at a depth of 5 km, assuming sea water has a constant specific weight of 10.1 kN m-³? Express your answer in kilopascals. The bathyscaphe contains several ballast tanks to regulate its buoyancy. If the dry mass of the bathyscaphe is 800 kg and its volume is 15 m³, the ballast tanks must contain what volume of seawater for the bathyscaphe to begin to sink? LF
