Reducing pipe refers to the pipe that connects pipe segments with different diameters in series in sequence. The pressure loss is equal to the sum of the pressure losses of each pipe section. It is often used when there are multiple branch pipes along the way. The pipe network is formed by gathering the inlet ends of several single pipes or series pipes and connecting the outlet ends. The pressure loss of fluid in each branch pipe is equal, and the flow at the pipe connection point is equal to the sum of the flow of each branch pipe. It is often used in situations where the throughput is very large or the expansion is repeated.
