Calculators

• Application Rate: Water
  application rate from a given flow
  and area
• Drip Line: Application rate
  of drip lines
• Application Depth: Calculate
  application depth given flow,
  land area, and time
• Required Flow Rate: Flow
  rate required to meet crop
  water demands for an area
  
  
• Handmove Sprinkler Lines:
  Comprehensive Calculator for hand-move
  and wheel-line irrigation systems
  
  
• Fertilizer Injection Rate:
  Calculate the injection rates for fertigation
  
  
• Nozzle Discharge and Size: Used
  to calculate the discharge of a nozzle or the
  the size required for a set pressure and flow
  
  
• Traveling Gun:
  Calculate the net water application for a
  traveling big gun sprinkler

• Unit Conversions
  
  

• Center Pivot Calculators:
  
  • Pivot Acreage: Calculate the area underneath a center pivot.
    
    
  • Time for Full Rotation: The time that it takes for a 360 degree rotation of a center pivot.
    
    
  • Approximate Percentage Timer Setting: Use this calculator to calculate a timer setting to apply a particular depth.
    
    
  • Time for 1" Application: Calculate the irrigation time to apply one inch of water with a center pivot.
    
    
  • Estimating System Pumping Requirements: Calculate the system capacity (flow rate) required to meet the demands of a field.
    
    
• Landscape Plants Requirements:
  Determine how much water
  to apply to individual plants with drip emitters
  
  
• Columbia Basin Available Water:Access bulk density and available water (water holding capacities) of Columbia Basin Soils.

• Pumping Power: Pump horse power requirements
• Sprinkler App. Rate: Sprinkler application rate based on nozzle diameter and spacing
• Pipe Velocity: Many designers design pipe sizes based on velocity limits (5 fps). Calculate water velocity in a pipe
• System Capacity:Calculate the system flow rate capacity required to meet crop water needs
  
  
• Flow over Trapezoidal Weir:Calculate flow rate over a trapezoidal (Cipolletti) weir.
  
  
• Pipe Friction: Pressure loss in
  pipes from friction
  
  
• Set Times:Calculate the set time for irrigating based on application and flow rate
  
  
• Pressure Loss with Outlets : Calculate the pressure loss in a pipe with evenly spaced outlets, such as a sprinkler lateral or a manifold, or minimum pipe size in the same based on the maximum allowable pressure loss
