1. corn requires 22 inches of water for a successful crop. a farmer that has a 200-acre farm is in a drought and receives only 2 inches of rain throughout the year.

(a) calculate how many gallons of water the farmer will need to purchase to be able to irrigate his crops. recall that 60% of the water applied to a field through irrigation is lost. (an acre-foot is a common unit for measuring volumes of water, typically used in irrigation calculations. one acre-foot is the volume of water sufficient to cover an acre of land to a depth of 1 foot, approximately 325,851 u. s. gallons.) show all work.

(b) discuss two effects on a small stream if the farmer were to pump irrigation water from it, decreasing the flow rate of the stream.

(c) discuss three ways the farmer could lessen the 60% loss of water while irrigating the farm.
