Irrigatable Area As Limited By Water Supply
This calculator finds the land area that can be irrigated with a given flow of water. The minimum system capacity (supply) is the available water from the supply. The water needs is the peak crop water need during a specific time period. The available hours of operation per day is measured as the available hours for irrigation on a worst case day. The system efficiency is based on the irrigation efficiency and distribution uniformity.
This calulator uses this formula to determine the Irrigatable area.
= Irrigatable Area (sq. ft)
= Minimum system capacity, or supply (gpm)
= Water needs (in/day)
= Operation hours per day (hrs)
= System Efficiency (as a decimal)
