Evaporation is the process by which water changes from a liquid state to a gaseous state. It is influenced by various factors such as temperature, humidity, wind speed, and surface area. Evaporation pans are commonly used to measure evaporation rates, and the data obtained from these pans can be used to estimate the evaporation loss from a reservoir.
Given data:
- Water surface area on a particular day = 100 ha
- Recorded evaporation loss from the pan on that day = 4 cm
To estimate the evaporation loss from the reservoir, we need to convert the recorded evaporation loss from the pan to the same units as the reservoir's surface area.
1. Convert the recorded evaporation loss from cm to meters:
- 1 cm = 0.01 m
- Recorded evaporation loss = 4 cm * 0.01 m/cm = 0.04 m
2. Calculate the evaporation loss from the reservoir:
- Evaporation loss from the pan is typically lower than the evaporation loss from a reservoir due to various factors such as wind, shading, and turbulence.
- Studies have shown that the evaporation loss from a reservoir can be around 1.2 to 1.4 times the evaporation loss from an evaporation pan.
Using the conversion factor of 1.2 to 1.4, we can estimate the evaporation loss from the reservoir:
- Minimum estimated evaporation loss from the reservoir = 0.04 m * 1.2 = 0.048 m
- Maximum estimated evaporation loss from the reservoir = 0.04 m * 1.4 = 0.056 m
3. Convert the estimated evaporation loss from meters to the desired units (104 m3/day):
- 1 m = 10,000 m3
- Minimum estimated evaporation loss = 0.048 m * 10,000 m3/m = 480 m3/day = 4.8 * 104 m3/day
- Maximum estimated evaporation loss = 0.056 m * 10,000 m3/m = 560 m3/day = 5.6 * 104 m3/day
Therefore, the anticipated evaporation loss from the reservoir for the day is approximately 3.0 to 3.25 * 104 m3/day, which corresponds to option C.
