Explanation:
An irrigation outlet is said to be proportional when its flexibility is equal to 1.
Flexibility:
Flexibility refers to the ability of an irrigation outlet to respond to changes in the water flow. It is a measure of how easily the outlet can be adjusted to deliver the desired amount of water.
Proportional Irrigation Outlet:
A proportional irrigation outlet is one that can deliver water in proportion to the changes in flow. This means that if the flow rate is increased or decreased, the outlet will adjust accordingly to deliver the appropriate amount of water.
Flexibility = 1:
When the flexibility of an irrigation outlet is equal to 1, it means that the outlet can perfectly adjust to changes in flow. It can deliver water in direct proportion to the changes in flow rate.
For example, if the flow rate is doubled, a proportional irrigation outlet with a flexibility of 1 will also double the amount of water it delivers. Similarly, if the flow rate is halved, the outlet will reduce the water delivery by half.
Therefore, a proportional irrigation outlet is one that can accurately and precisely adjust its water delivery in response to changes in flow rate, making it highly efficient and effective in irrigation systems.
Therefore, the correct answer is option 'B' - Flexibility = 1.
