Calculation for 1" of water

Plants need 1-2" of water per week. Some areas are lucky enough to get rain. =(
Here is the calculation to figure out how much water to apply to equal 1" of rain.
Adjust the speed of the water flow so you can fill a 1 gallon container in 30 seconds. Possibly you can indicate that on the spicket with a permanent marker or a twist tie. At that rate of water flow, it will take 30 minutes of watering to apply 1" of water to 100 square feet.
