Group I lists a few devices while Group II provides information about their uses. Match the devices with their corresponding use. Group I P. Anemometer Q. Hygrometer R. Pitot Tube S. Tensiometer Group II 1. Capillary potential of soil water 2. Fluid velocity at a specific point in the flow stream 3. Water vapour content of air 4. Wind speed

1. P - 1; Q - 2; R - 3; S - 4
2. P - 2; Q - 1; R - 4; S - 3
3. P - 4; Q - 2; R - 1; S - 3
4. P - 4; Q - 3; R - 2; S - 1

Correct answer: P - 4; Q - 3; R - 2; S - 1

Solution

The correct option matches each device with its specific function: the anemometer measures wind speed, the hygrometer assesses the water vapor content in the air, the Pitot tube determines fluid velocity at a point in a flow stream, and the tensiometer evaluates the capillary potential of soil water.
