Question

A liquid is allowed into a tube of truncated cone shape. Identify the correct statement from the following.

• A. The speed is high at the wider end and low at the narrow end
• B. The speed is low at the wider end and high at the narrow end
• C. The speed is same at both ends in a streamline flow
• D. The liquid flows with uniform velocity in the tube

Answer 1

The correct option is B The speed is low at the wider end and high at the narrow end

For an incompressible liquid equation of continuity
AV$=$constant or A$\propto \frac{1}{V}$
Therefore, at the wider end speed below and at the narrow end speed will be high.
