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

11.If the weight of a body immersed in a fluid exceeds the buoyant force, then the body will

rise until its weight equals the buoyant force
tend to move downward and it may finally sink
float
none of the above

12.The viscosity of a gas

decreases with increase in temperature
increases with increase in temperature
is independent of temperature
is independent of pressure for very high pressure intensities

13.A floating body is said to be in a state of stable equilibrium

when its metacentric height is zero
when the metacentre is above the centre of gravity
when the metacentre is below the centre of gravity
only when its centre of gravity is below its centre of buoyancy

14.Flow at constant rate through a tapering pipe is i) steady flow ii) uniform flow iii) unsteady flow iv) non-uniform flow The correct answer is

(i) and (ii)
(i)and(iv)
(ii) and (iii)
(ii) and (iv)
