Question:
A liquid is flowing through a non-sectional tube with its axis horizontal. If two points X and Y on the axis of tube have sectional area 2.0 cm² and 25 mm² respectively then find the flow velocity at Y when the flow velocity at X is 10 m/s.

The Correct Option is C
Solution and Explanation
Step 1: Convert areas: AX = 2.0 cm² = 200 mm²
Step 2: Using continuity equation, AX vX = AY vY
Step 3: 200 × 10 = 25 × vY vY = 80 m/s
