水流量怎么计算

To calculate water flow rate, you can use the formula:

\[ \text{Flow Rate} = \text{Area} \times \text{Velocity} \]

Where:
- Flow Rate is the volume of water passing through a given point in a specified amount of time (measured in cubic meters per second, liters per minute, etc.).
- Area is the cross-sectional area through which the water is flowing (measured in square meters).
- Velocity is the speed at which the water is flowing through the area (measured in meters per second).

You can measure the area and velocity of the water flow to calculate the flow rate.
