Water Delivery Calculator

Water Delivery Formula

The formula to calculate the amount of water needed per month is:

\[ W = \frac{(64 \times \frac{H}{16}) \times P}{128} \times 30 \]

Where:

• W is the amount of water needed per month (in gallons).
• H is the number of hours people spend in the building per day.
• P is the total number of people in the building.

Example Calculation

If there are 10 people in the building, each spending 8 hours per day:

\[ W = \frac{(64 \times \frac{8}{16}) \times 10}{128} \times 30 = 60 \text{ gallons per month} \]

Understanding the Calculation

• Each person typically needs 64 ounces (1/2 gallon) of water per day.
• If people spend 8 out of 16 waking hours in the building, they need at least 32 ounces (1/4 gallon) while there.

How to Calculate Water Delivery

Use the formula to estimate the total gallons required monthly based on the time spent and the number of people present.

Common Questions

1. How much water should I provide per person?

   • On average, each person needs 64 ounces of water per day.

2. Why divide by 128 in the formula?

   • There are 128 ounces in a gallon, so this converts daily water consumption to gallons.

3. How can I ensure enough water is delivered?

   • Ensure that calculations account for all people and adjust if the building's occupancy changes.
