Question

A cylindrical pipe has a radius of \( 0.1 \, \text{m} \). If the speed of water flowing through the pipe is \( 2 \, \text{m/s} \), calculate the volume flow rate of water through the pipe.

• A. \( 0.0628 \, \text{m}^3/\text{s} \)
• B. \( 0.0314 \, \text{m}^3/\text{s} \)
• C. \( 0.1256 \, \text{m}^3/\text{s} \)
• D. \( 0.02 \, \text{m}^3/\text{s} \)

Hint:

The volume flow rate is directly proportional to the cross-sectional area and the velocity of the fluid. Larger pipes or faster flowing fluids result in higher flow rates.
