Final answer:
The rate at which automatic fill pumps fill gravity tanks typically must be determined based on specific factors like pump strength and system requirements. In physics, this involves calculations using fluid dynamics principles.
Step-by-step explanation:
The question pertains to the functionality of automatic fill pumps and the rate at which they can supply water to gravity tanks. This information is typically measured in gallons per minute (gpm). However, the specific fill rate of an automatic fill pump can vary widely depending on the pump's design and the requirements of the system it serves. For example, the rate described in scenarios like a sump pump draining a basement or a pump supplying water to a pipeline will depend on various factors including the pump's power, the height water is being lifted to, and any resistance faced within the piping system.
To answer similar questions about flow rate in specific scenarios, one would apply principles of fluid dynamics, such as Bernoulli's equation or Poiseuille's Law, to calculate the flow rate given certain pressures, forces, and pipe diameters.
