APJ ABDUL KALAM TECHNOLOGICAL UNIVERSITY
THIRD SEMESTER B.TECH DEGREE EXAMINATION(S), May 2019

Course Code: CE203
Course Name: FLUID MECHANICS - I

PARTA
Answer any two full questions, each carries 15 marks.
A cylinder contains a fluid at a gauge pressure of 350 kN/m?. Express the
pressure in terms of head of (a) water, (b) mercury. What would be the absolute
pressure in the cylinder if the atmospheric pressure is 101.3 kKN/m??
An annular ring cut in a sheet metal has 1.5 m outer diameter and 1.0 m inner
diameter. It is inserted vertically in a liquid of relative density 0.90 with its centre
1.75 m below the surface. Calculate the total force on one side of this ring and
the location of the centre of pressure.
A ship 60 m long and 10 m wide displaces 15000 KN of water. A weight of 200
KN is displaced across the deck through a distance of 5 m and the ship is tilted
through 4.50, The moment of inertia of the ship about the fore - and - aft axis is
80 % of the circumscribing rectangle. The centre of buoyancy is 2 m below the
water surface. Determine the metacentric height and the position of the centre of
gravity of the ship. Take specific gravity of water as 1.03.
Show that the streamlines and equipotential lines form a net of mutually
perpendicular lines.
Differentiate between the Eulerian and Lagrangian methods of representing fluid
flow.
The stream function for a flow field is represented by ٢ = 2xy. Show that the
flow exists and is irrotational.
Distinguish between:
(i) Steady flow and Unsteady flow.
(ii) Uniform flow and Non uniform flow.
