Final answer:
Correctly sized vacuum lines are essential for an evacuation system, and they need to be equal to or larger than the pump intake connections to ensure effective operation and prevent system damage. The answer to the question is true option a.
Step-by-step explanation:
The question posed is about the appropriate sizing of vacuum lines in an evacuation system, compared to the pump intake connections. To ensure efficient and safe operation of an evacuation system, it is generally recommended that the vacuum lines (hoses) should be equal to or larger than the pump intake connections. This helps in preventing bottlenecks that could restrict air flow and diminish the performance of the pump, potentially leading to increased wear or even damage over time. The statement that vacuum lines should be equal to or larger than the pump intake connection is therefore true.
Vacuum technology is often utilized in various applications such as power brake systems in vehicles, as well as heavy machinery like bulldozers. Factors that influence the efficiency of these systems include line size, hose material, pressure conditions, and the power of the vacuum pump itself. In such systems, proper maintenance of pressure is crucial for performance, hence why correctly sized vacuum lines are mandatory.
In summary, for the given question related to the evacuation system's required hose sizing, the correct answer would be true, indicating that the vacuum lines should be at least as large as the pump intake connections to function correctly.
