Final answer:
An outlet baffle allows for the transition of water from a high-speed flow to a slower one in a wastewater system. The continuity equation in fluid dynamics helps predict the changes in speed of the fluid due to varying cross-sectional areas, but more information is required to calculate the emerging speed of water from a pipe pushed by a given force.
Step-by-step explanation:
An outlet baffle is created from the transition of the faster flowing wastewater to a slower horizontal flow that may cause the pipe to fill momentarily. When considering fluid dynamics in a pipe system, the equation of continuity is a key principle. It states that for an incompressible fluid with a constant density, the speed of the fluid will increase when the cross-sectional area of the flow decreases, and conversely, speed decreases when the cross-sectional area increases.
In the scenario provided, where a pipe has a diameter of 5.6 cm and the water is being pushed by a plunger with a force of 440 N, we would need to use the principles of fluid dynamics, specifically the continuity equation and Bernoulli's principle, to calculate the emerging speed of the water. However, since the necessary information to perform the calculations such as the length of the pipe and friction factors are not provided, it is not possible to accurately determine the speed without making assumptions.
