Water Supplies - Expected vs. Theoretical Summarized Demand

Calculate the expected total water flow for a water supply system based on the total theoretical demand and the largest consumer demand. The formula accounts for intermittent use patterns in ordinary systems like homes, offices, and nursing homes.
