Hydraulics McQ Chapter Wise Online Test of 25 Question #7

1. Weir may also be used to measure

2. Water in open channel and streams is measured through

3. The sheet of water flowing through a notch or over a weir is known as

4. The upper surface of weir over which water flows is known as

5. The upper surface of weir over which water flows is known as

6. The discharge through V-notch weir is directly proportional to

7. The side slope of Cipolletti weir is generally kept

8. The thickness of a sharp crested weir is kept less than

9. In a broad crested weir, width of crest of the weir will be

10. The discharge over a broad crested weir is maximum when the depth of flow is

11. The discharge over a broad crested weir is maximum when the depth of flow is

12. In case of broad crested weir, the depth of water h at the end of sill is given by

13. In order to avoid cavitation the upstream edge of broad crested weir should have

14. Due to each end contraction, the discharge of rectangular sharp crested weir is reduced by

15. When level of water on the downstream side of a weir is above the top surface of the weir, the weir is known as

16. Crest of weir is lower than downstream water level:

17. If weir is used as a spillway it will have a crest

18. The length of a pipe is 1 km and its diameter is 20 cm. If the diameter of an equivalent pipe is 40 cm, then its length is

19. The basic head loss in pipe is due to

20. For laminar flow In circular pipes, the Darcy’s friction factor f is equal to

21. For hydro-dynamically smooth boundary, the friction coefficient for turbulent flow is

22. Head loss increases with

23. The head loss in turbulent flow in pipe

24. Losses are more in

25. Two pipes of same length and diameters d and 2d respectively are connected in series. The diameter of an equivalent pipe of same length is.
