A horizontal pipe of 30.0 cm² cross-sectional area carries water at a speed of 2.5 m/s. This pipe feeds a smaller pipe of cross section 10.0 cm². Find the speed of water flow in the smaller pipe.

Question

According to the principle of continuity for incompressible fluids, the product of cross-sectional area and velocity is constant. Therefore, (30 cm²)(2.5 m/s) = (10 cm²)(v), solving for v gives v = 7.5 m/s.
