In the United States, water used for irrigation is measured in acre-feet. An acre-foot of water covers an acre to a depth of exactly 1 foot. An acre is 4840 yd^2.
If desalinated water costs $1950 per acre-foot, how much does desalinated water cost per liter?
Convert 4840 square yards to square feet and that to cm^2. Convert 1 foot to cm. Calculate volume in cc and that will be in liters. The cost will be $1950/??liters. Convert to 1L.
To find out how much desalinated water costs per liter, we need to convert the volume from acre-feet to liters and then divide the cost by the volume.
Step 1: Convert acre-feet to liters
To convert acre-feet to liters, we need to know the conversion factors:
1 acre-foot = 1233.48 cubic meters
1 cubic meter = 1000 liters
Therefore, 1 acre-foot = 1233.48 cubic meters * 1000 liters = 1,233,480 liters
Step 2: Calculate the cost per liter
Now that we know that 1 acre-foot is equivalent to 1,233,480 liters, we can divide the cost of desalinated water by the volume to find the cost per liter.
Cost per liter = Cost of desalinated water / Volume in liters
Given that the cost of desalinated water is $1950 per acre-foot, we can substitute the values into the equation:
Cost per liter = $1950 / 1,233,480 liters
By performing this calculation, we find that desalinated water costs approximately $0.00158 per liter.
