Task 2
Determine the up-thrust on an immersed body
Mooring rope
Buoy diameter = 0.6m
A spherical buoy of diameter 0.6 m and mass 40 kg is attached to the seabed by a
mooring rope and floats fully submerged as shown above. Calculate the tension in the
mooring rope. The density of freshwater is 1020 kg/m'.

Task 3
Use the continuity of volume and mass flow for an incompressible fluid to determine the
design characteristics of a gradually tapering pipe
0 600 mm
Direction of flow
6 250 mm
The pipe shown above is running full with oil of relative density 0.87 and flow velocity at the
entry to the tapered section of 1.5 m/s. The diameter at the entrance of the pipe is 600 mm and
diameter at exit is 250 mm. Find the flow velocity at the exit from the tapered section and mass
flow rate of the oil. The density of water is 1000 kg/m3.
