A. Minimum daily flow / average daily flow - 4. (2/3) (or 0.67):
The minimum water demand on any single day of the year drops down to roughly two-thirds (67%) of the overall annual average daily demand.
B. Minimum hourly flow / average daily flow - 1. (1/3) (or 0.33): During the late-night or early-morning hours, water consumption drops to its absolute lowest, typically hitting about one-third (33%) of the average daily flow.
C. Maximum daily flow / average daily flow - 2. (2) (or 1.8): The peak water consumption on the highest-demand day of the year usually spikes to approximately (1.8) to (2.0) times the average daily flow.
D. Maximum hourly flow / average daily flow - 3. (3) (or 2.7): The peak hourly water demand during morning rush hours on the maximum consumption day spikes sharply, reaching around (2.7) to (3.0) times the average daily flow.
