The high-level tank has a capacity of 5 m3, and the pipes used are stainless steel with a diameter of DN40. The water flows from this tank to a measurement tank. The height difference between the high-level tank and the measurement tank is 2 meters, with the liquid level in the high-level tank being at a height of 2 meters. What should be the flow rate of the water inside the DN40 pipe at the inlet of the measurement tank? How should pipeline resistance be considered? Please take the time to guide us, experts.
It is recommended to pick up a book on \"Principles of Chemical Engineering\"; the chapter on fluid transport provides very comprehensive information.
One is to consider the pipe diameter, as well as the process issues.
The previous edition of Chemical Engineering Principles published by Tianjin University had similar examples; you can take a look
There is a formula that includes g and an opening symbol. To understand this issue, it is sufficient to determine whether the maximum flow rate required can be met; the actual flow rate depends on the valve opening degree and therefore cannot be estimated
The theoretical value can be calculated based on this, but it’s really difficult to estimate the pipeline resistance; it depends on factors such as the fluid state, the degree of valve opening, and the length of the pipeline
