Question

An identical liquid is flowing in a tube A of small variable cross-section Tube 1, Tube 2 and Tube 3 is connected at point 1, 2 and 3 respectively as shown Let $h_1,h_{2}and{h}_3$ are the final heights of liquid in tube 1, 2 and 3 respectively and $v_1,v_{2}and{v}_3$ are the velocity of the liquid at cross-section 1, 2 and 3 respectively Match the quantities in List I and List II

Answer 1

As the area of cross-section increases, velocity decreases, and the pressure increase. Therefore, the $h_1$ is greater than $h_3$ and $h_2$ is less than $h_3.$

As the area of cross-section of the part $1$ is large so it has the least velocity and the velocity is maximum for part $2$ since its area of cross-section is least.

So, $v_2>v_3>v_1$
