Final answer:
The rate of water flow can be estimated using the equation Q = A×v. To approximate the average rate of water flow during a specific time period, you can use the equation w(t) = Q×t where w(t) represents the approximate average rate and t represents the duration. The units of measure will depend on the units used for area and velocity.
Step-by-step explanation:
The rate of water flow, also known as flow rate, can be estimated using the equation Q = A×v, where Q is the flow rate, A is the cross-sectional area of the pipe or hose, and v is the average velocity of the water flow.
To approximate the average rate of water flow during an 8-hour time period, you can use the equation: w(t) = Q×t, where w(t) is the approximate average rate of water flow and t is the duration of time (in this case, 8 hours).
The units of measure for the flow rate will depend on the units used for the area (A) and velocity (v), such as cubic meters per second (m³/s) when using the metric system.
