Use gas cylinders to pressurize the pipeline; how many cylinders are needed
Thread Content
The pipeline needs to undergo a pressure test. It is to be pressurized using 40L nitrogen cylinders at 10MPa. The diameter of the pipeline is DN300, and its length is 715 meters; the required test pressure is 1.73MPa. How many cylinders are needed?

You can calculate the total volume of the pressurization pipeline and the amount of nitrogen required; you can also determine the amount of high-pressure nitrogen stored in each cylinder, and from that, the amount of ice can be calculated. Don’t say you study the humanities.
