How fast will the pivot get around for a given application rate?
Trevolution= [ Qpump / 450] / [ Area x Idepth ]
where,
Idepth = depth applied per revolution, inches
Qpump = irrigation system flow rate, gallons per minute
Efficiency = Application efficiency of system
Trevolution = revolution time, hours
Area = irrigated area, acres
System flow rate 675 Gallons per minute
Application Depth 0.75 Inches per acre
Irrigated area 130 Acres
Application Efficiency 100% Percentage
Gallons in acre inch 27,154 Gallons
Acre inches pumped each hour 1.50 Inches per acre
Total Acre Inches Needed for pivot 98 Acre Inches
Conversion Constant 450 Constant
Total amount of time to make revolution 65.0 Hours
Total amount of time to make revolution 2.71 Days
