A horizontal pipe has a diameter of 10.0 cm fluid flows in the pipe at 0.500 m/s The pipe is attached to a smaller pipe that has a diameter of 4.00 cm what is the speed of the fluid in the smaller pipe? |

Answer» 25cm/sStep-by-step EXPLANATION:Rate of flow, A * V, must remain CONSTANT. Use the continuity equation, A1v1=A2v2.Solving the initial cross-sectional AREA yields: A1=πr2=25πcm2. The initial radius is 5cm.Then find the final area of the pipe: A2=πr2=9πcm2. The final radius is 3cm.Using these values in the continuity equation allows us to solve the final velocity.(25πcm2)(9cm/s)=(9πcm2)v2v2=25cm/s |
