Question

The amount of liquid flowing per second in the tubes (1), (2) and (3) are 10 m3/s, 5 m3/s and 8 m3/s respectively. The velocity of liquid in the tube (4) having cross-section of 0.5 m2 is (A) 7 m/s (B) 14 m/s (C) 3.5 m/s (D) 12 m/s

Q4 + 10 +5 -8 = 0 Q4 = 7m3/s ∴ 0.5v = 7 v = (7/0.5) = (70/5)=14 m/s

Q. The amount of liquid flowing per second in the tubes (1), (2) and (3) are 10 $m^{3} / s$ , $5 m^{3} / s$ and $8 m^{3} / s$ respectively. The velocity of liquid in the tube (4) having cross-section of $0.5 m^{2}$ is

7 m/s

14 m/s

3.5 m/s

12 m/s

$Q_{4} + 10 + 5 - 8 = 0$
$Q_{4} = 7 m^{3} / s$
$∴ 0.5 v = 7$
$v = \frac{7}{0.5} = \frac{70}{5} = 14 m / s$
