A pipe has a cross-sectional area of 2.0 cm². If water moves through it at a speed of 5.0 m/s, what is the volume flow rate?
Q1. A pipe has a cross-sectional area of 2.0 cm². If water moves through it at a speed of 5.0 m/s, what is the volume flow rate?
Answer: 0.001 m³/s
Explanation: Flow rate Q = Area * velocity. Converting 2.0 cm² to 0.0002 m², Q = 0.0002 * 5 = 0.001 m³/s. Option B uses cm² directly.
