Water (γw = 9.879 kN/m3) flows with a flow rate of 0.3 m3 /sec through a pipe AB of 10 m length and of uniform cross section. The end ‘B’ is above end ‘A’ and the pipe makes an angle of 30° to the horizontal. For a pressure of 12 kN/m2 at the end ‘B’, the corresponding pressure at the end ‘A’ is
-
- 12.0 kN/m2
- 17.0 kN/m2
- 56.4 kN/m2
- 61.4 kN/m2
Correct Option: D
Apply Bernoulli’s equation,
| = | + ZB | ||
| r | r |
| = | + 5 = 6.214 | |
| 9.879 |
∴ Pa = 6.214 × 9.879
= 61.4 kN/m².
