Mechanical Engineering : Hydraulic And Fluid Machines QUESTIONS AND ANSWERS :: part8 : 16 to 20

Following Mechanical Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2024 and IES 2024 examinations :

16.Uniform flow occurs when

the direction and magnitude of the velocity at all points are identical
the velocity of successive fluid pai-ticles, at any point, is the same at suc�cessive periods of time
the magnitude and direction of the velocity do not change from point to point in the fluid
the fluid particles move in plane or parallel planes and the streamline pat-terns are identical in each plsr.e
velocity, depth, pressure, etc. change from point to point in the fluid flow.

17.In a forced vortex, the velocity of flow everywhere within the fluid is

maximum
minimum
zero
non-zero finite
unpredictable.

18.All the terms of energy in Bernoulli's equation have dimension of

energy
work
mass
length
time.

19.A streamline is defined as the line

parallel to central axis flow
parallel to outer surface of pipe
of equal yelocity in a flow
along which the pressure drop is uniform
which occurs in all flows.

20.The region between the separation streamline and the boundary surface of the solid body is known as

wake
drag
lift
boundary layer
aerofoil section.
