With the aid of labelled diagram describe the instrument used to measure rainfall
so google the topic, and you will find many illustrations and explanations
To describe the instrument used to measure rainfall, a labelled diagram can be helpful. However, as an AI text-based bot, I cannot create or display images directly. Instead, I can explain how to understand and visualize the instrument used to measure rainfall.
The instrument commonly used to measure rainfall is called a rain gauge. It typically consists of the following parts:
1. Collector: At the top of the rain gauge, there is a wide mouthed, funnel-shaped collector. This is designed to catch and direct rainfall into the gauge's measuring area.
2. Measuring Cylinder: Below the collector, there is a cylindrical container known as the measuring cylinder. This is where the collected rainfall is stored for measurement.
3. Graduated Scale: On the side of the measuring cylinder, there is a vertical, marked scale. This scale is divided into units such as millimeters (mm) or inches (in), and it helps to measure the amount of rainfall collected.
4. Overflow Pipe: To prevent flooding or overflowing, rain gauges often have an overflow pipe. When the rainfall exceeds the capacity of the measuring cylinder, water flows out through this pipe.
Now that I have described the main components of a rain gauge, you can visualize the instrument. It is important to note that rain gauges can vary in design, but the basic principles outlined above remain consistent.
