(b) change point
(c) reduced level
(d) station
Ans. (a)

Q2. When the flow in an open channel is gradually varied, the flow is said to be
(a) steady uniform flow
(b) steady non-uniform flow
(c) unsteady uniform flow
(d) unsteady non-uniform flow
Ans. (b)

Q3. Which of the following is a non-recording raingauge?
(a) Symon’s raingauge
(b) Tipping bucket type raingauge
(c) Weighing type raingauge
(d) Floating type raingauge
Ans. (a)

Q4. Minimum pitch of rivets shall not be less than
(a) 1.5d
(b) 2.0d
(c) 2.5d
(d) 3.0d
Ans. (c)
Sol. As per IS 800 : 2007, clause 10.2.2, The distance between centre of fasteners shall not be less than 2.5 times the nominal diameter of the fastener.


Q5. Lining of irrigation canals
(a) decreases the water logging area
(b) increases the water logging area
(c) does not change the water logging area
(d) increases evaporation
Ans. (a)

Q6. The entrance length for fully developed turbulent flow is:
(a) Le = 50 D
(b) Le = 0.71 D
(c) Le = 0.05 D
(d) Le = 23.5 D
Ans. (a)
Sol. As per formula, Le/D = 0.07 Re : for laminar flow and Le/D = 50 for turbulent flow.

Q7. During the obstruction in a pipe, loss of energy takes place due to:
(a) Increase in pressure at obstruction point
(b) Reduction in area of cross section at point of obstruction
(c) Increase in discharge at point of obstruction
(d) Decrease in discharge at point of obstruction
Ans. (b)
Sol. During obstruction in a pipe, loss of energy always takes place due to reduction in area of cross section of pipe where the obstruction is present and beyond that there will be sudden enlargement of area of flow due to which head loss will occur.

Q8. A pipe of length more than double the diameter of the orifice fitted internally or externally to the orifice is called
(a) Notch
(b) Weir
(c) Mouthpiece
(d) Nozzle
Ans. (c)
Sol. The pipe of length more than double the diameter of the orifice fitted internally or externally to the orifice is called mouthpiece.


Q9. The distance between two consecutive rivets which is measured perpendicular to the direction of force is known as:
(a) Gauge distance
(b) End distance
(c) Edge distance
(d) Pitch
Ans. (a)
Sol. Gauge distance is the distance between two consecutive rivets which is measured perpendicular to the direction of force.

Q10. The value of maximum effective slenderness ratio for a steel member carrying compressive loads resulting from dead loads and live loads is:
(a) 200
(b) 180
(c) 150
(d) 300
Ans. (b)

Sol. As. Per IS 800 : 2007, clause 3.8, the value of slenderness ratio for a beam, sturt or tension member carrying compressive loads resulting from dead loads and live loads shall not exceed 180.
