Final answer:
The question involves calculating the flow rate of water draining from a tank, using the volume and the time provided. It is a high school-level physics problem involving fluid dynamics and the application of Bernoulli's equation for more complex systems.
Step-by-step explanation:
To solve such a question, we would typically use the formula for flow rate, which is the volume of fluid passing through a surface per unit time. In this case, you have a tank holding 1000 gallons of water draining in half an hour, which gives a flow rate of 2000 gallons per hour (since 1000 gallons in 30 minutes is equivalent to 1000 gallons / 0.5 hours).
For a more complex scenario, like a sump pump draining water at a certain rate and pressure, you would need to know the physics equations that relate pressure, flow rate, and hose dimensions. This involves using Bernoulli's equation and principles of fluid dynamics to calculate parameters such as the change in pressure at different points in the hose system.
