Question

Water flows through a circular tube which transverse section has a diameter of 0.3 m. What speed will the water have inside the tube if the flow is 1.20 m3/s?

Answer 1

With diameter 0.3 m, the cross-sectional area is π (0.3 m)² ≈ 0.283 m². Then the water leaves the pipe with speed

(1.20 m³/s) / (0.283 m²) ≈ 4.24 m/s
