One end of a cylindrical pipe has a radius of 1.5 cm. Water (density = 1.0 *10³ kg/m³) streams steadily out at 7.0 m/s. The volume flow rate is: A) 4.9 * 10^-³ m³/s B) 2.5 m³/s C) 4.9 m³/s D) 7.0 m³/s E) 48 m³/s

Question

Quizplus · Accepted Answer

The volume flow rate is calculated using the formula Q = A * v, where A is the cross-sectional area of the pipe and v is the velocity of the water. The area A = π * r² = π * (0.015 m)². Thus, Q = π * (0.015 m)² * 7.0 m/s ≈ 4.9 x 10⁻³ m³/s.
