The water distribution efficiency is 1.0 if _____a)the deviation from ...
It represents the extent to which the water has penetrated to a uniform depth throughout the area. If the water penetrates uniformly throughout the field, the deviation from the mean depth is zero and hence, water distribution efficiency is 1.0.

Water Distribution Efficiency

Water distribution efficiency is a term used in civil engineering to measure the effectiveness of a water distribution system in delivering water to consumers. It is represented by a value between 0 and 1, where 1 indicates a perfectly efficient system and 0 indicates a completely inefficient system.

Mean Depth and Deviation

To understand why the correct answer is option 'B', let's first discuss the concepts of mean depth and deviation. Mean depth refers to the average depth of water in a distribution system. Deviation, on the other hand, measures the variation or difference between individual depths and the mean depth.

Option 'A': Deviation from the Mean Depth is 1

If the deviation from the mean depth is 1, it means that the individual depths are varying by 1 unit from the mean depth. This indicates that there is some variation in the water levels within the system. However, this alone does not guarantee a water distribution efficiency of 1.0.

Option 'B': Deviation from the Mean Depth is 0

When the deviation from the mean depth is 0, it means that all the individual depths are equal to the mean depth. In other words, there is no variation in the water levels within the system. This indicates a perfectly balanced and efficient distribution of water.

Option 'C': Deviation from the Mean Depth is Less than 1

If the deviation from the mean depth is less than 1, it means that the individual depths are varying by a value less than 1 unit from the mean depth. While this indicates some level of efficiency, it does not guarantee a perfect efficiency of 1.0.

Option 'D': Deviation from the Mean Depth is Greater than 1

When the deviation from the mean depth is greater than 1, it means that the individual depths are varying by a value greater than 1 unit from the mean depth. This suggests a significant variation in the water levels within the system, indicating a lower level of efficiency.

Conclusion

Based on the above analysis, it is evident that the correct answer is option 'B' - the deviation from the mean depth is 0. A deviation of 0 indicates a uniform and consistent distribution of water, resulting in a water distribution efficiency of 1.0.
