The level of water in the reservoir is 1.25 m. If there is a rainfall of 38 cm occurring in a month, during this period evaporation as measured by the class A pan is 32 cm. What is the level of water in m at the end of the month.
  • a)
    1.4
  • b)
    1.41
Correct answer is between '1.4,1.41'. Can you explain this answer?
Verified Answer
The level of water in the reservoir is 1.25 m. If there is a rainfall...
Evaporation in lake = Pan coefficient × Pan evaporation
= 0.7 × 32 = 22.4 cm
Initial level + Rainfall – Evaporation = Final level
Final level = 1.25 + 0.38 – 0.224 = 1.406 m

The level of water in the reservoir is 1.25 m. If there is a rainfall...
Given data:
- Initial level of water in the reservoir = 1.25 m
- Rainfall in a month = 38 cm
- Evaporation measured by class A pan = 32 cm

To find: Level of water in meters at the end of the month

Solution:

Step 1: Convert the given data to meters
- Rainfall in meters = 38 cm = 38/100 = 0.38 m
- Evaporation in meters = 32 cm = 32/100 = 0.32 m

Step 2: Calculate the net change in the level of water
The net change in the level of water can be calculated by subtracting the evaporation from the total water input (rainfall).

Net change in the level of water = Rainfall - Evaporation
= 0.38 m - 0.32 m
= 0.06 m

Step 3: Calculate the final level of water
The final level of water can be calculated by adding the net change in the level of water to the initial level of water.

Final level of water = Initial level of water + Net change in the level of water
= 1.25 m + 0.06 m
= 1.31 m

Step 4: Round the final level of water to the nearest hundredth
Rounding the final level of water to the nearest hundredth gives us a value between 1.4 and 1.41.

Therefore, the correct answer is between 1.4 and 1.41 (option b).
