Which one of the following is the water flow for one acre-inch-day?

Solution

acre-inch-day is equal to: 1 acre-inch / 1 day / 1 acre To convert acre-inch to cubic feet, we use the conversion factor that 1 acre-inch is equal to 27,154.9 cubic feet. Therefore, the flow rate can be calculated as follows: 1 acre-inch / 1 day / 1 acre = 27,154.9 cubic feet / 1 day / 1 acre Simplifying the units, we get: 27,154.9 cubic feet / day / acre So, the water flow for one acre-inch-day is approximately 0.042 cubic feet per second (c ft/sec).
