An incompressible fluid (density of 920 kg/m³) flows at 10.0 m/s through a level pipe with a cross-sectional area of 1.5 cm². The pressure of the fluid in this section of the pipe is 150 kPa. The pipe is connected to a second pipe whose cross-sectional area is 2.5 cm². The speed of the flow in the second pipe is A) 8.0 m/s. B) 6.0 m/s. C) 10. m/s. D) 12 m/s.

Question

Quizplus · Accepted Answer

According to the principle of continuity for incompressible fluids, the flow rate must remain constant. Therefore, A1 * V1 = A2 * V2. Solving for V2 gives (1.5 cm² * 10.0 m/s) / 2.5 cm² = 6.0 m/s.
