What is the disadvantage of using a wide-angle pattern on a fixed firefighting system?

Explanation:
A wide-angle spray spreads water over a larger area, so the jet’s forward velocity drops and more energy is used to cover a wide arc rather than push water far. With the same discharge pressure, this reduces how far the water can reach, making reach shorter. This pattern is useful for covering a broad area up close, but you lose distance. The other options aren’t the main drawback: wider patterns don’t inherently increase reach, and water usage or nozzle life isn’t the primary consequence of changing the pattern in a fixed system.
