Final answer:
The rate at which automatic fill pumps fill a tank varies depending on factors such as pump power, design, and application.
Step-by-step explanation:
The question is asking about the rate at which automatic fill pumps fill a tank. As a tutor, I'm assuming you are searching for the minimum rate at which these pumps operate. Unfortunately, the information provided in the question does not specify the exact rate. However, I can help you understand the concept of flow rate and how it applies to pumps.
Flow rate is a measure of how much fluid (in this case, water) is moving through a system per unit of time. It is typically measured in gallons per minute (GPM) or liters per second (L/s). When a pump is described as filling a tank at a certain rate, it means that it can deliver fluid into the tank at a specific flow rate or higher. For example, if a pump has a specified flow rate of 10 GPM or more, it means it can fill the tank at a rate of 10 GPM or higher.
Without specific information about the pump mentioned in the question, I cannot provide the exact flow rate. However, the rate at which automatic fill pumps fill a tank can vary depending on factors such as the pump's power, design, and intended application.
