A tube of length $L$ is shown in the figure. The radius of cross section at the point (1) is 2 cm and at the point (2) is 1 cm , respectively. If the velocity of water entering at point (1) is $2 m / s$ , then velocity of water leaving the point (2) will be

Options:

Answer:

Solution:

$A_{1} V_{1} = A_{2} V_{2} \Rightarrow 2 π (2 R)^{2} = V_{2} π R^{2} ∴ V_{2} = 8 m / s$
