Question: 1 / 400

As the arcs of sprinklers double, what else should also increase?

Area coverage

Water temperature

Flow

When the arcs of sprinklers double, the flow of water should also increase to maintain the same level of irrigation efficiency across the expanded area. Doubling the sprinkles' arcs implies that the coverage area has significantly increased, which demands a higher volume of water to ensure that all areas are adequately irrigated.

As the area coverage expands, the system must provide sufficient water flow to saturate the larger space effectively. If the flow does not increase proportionally, some areas may receive inadequate moisture, leading to uneven irrigation and potentially harming the landscape's health.

Water temperature, pressure, and other factors may influence irrigation systems, but they do not need to match the increase in coverage arcs in the same direct way as flow does. Therefore, increasing flow is essential to achieving the desired uniformity and efficiency in irrigation as the sprinkler coverage doubles.
