Final answer:
Booster stations for oil and gas pipelines are typically placed every 60 to 100 kilometers for oil, and around 60 to 150 kilometers for natural gas, though these distances can vary based on numerous factors.
Step-by-step explanation:
The distance at which a booster station is needed to pump gas or oil can vary depending on a number of factors, including the diameter of the pipe, the viscosity of the fluid being pumped, and the terrain over which the pipeline runs. In general terms, booster stations for oil pipelines are typically placed every 60 to 100 kilometers. However, this is a simplified estimation as the actual distance may require a more precise calculation that involves the hydraulic gradient, frictional losses, and the economics of pipeline construction and maintenance.
For gas pipelines, the distance between booster stations can be influenced by factors such as pipeline pressure, diameter, and gas compressibility. The distance between compressor stations in natural gas pipelines is typically around 60 to 150 kilometers, but this varies widely depending on the system design and operational requirements.
Unfortunately, without specific data on pipeline characteristics and operational goals, it is not possible to provide an exact distance for when a booster station is needed. In the context of an assignment or exam, you would rely on textbook information or specific instructions provided in the course materials.
