General Design Calculators

Select a General Design Calculator

• Irrigatable Area: The land area that can be irrigated with a given flow of water.
• Irrigation Frequency: The maximum interval allowed between irrigations.
• Irrigation Run Time: Determine the length of time that an irrigation system must run to apply enough water to replace the water lost to evapotranspiration.
• Required Water Pump Horsepower: Estimate the brake horsepower and total power (hp) requirements of the electric motor used to power an irrigation water pump.
• Irrigation System Pumping Requirements: Calculate the system capacity (flow rate) required to meet the demands of a field.
• NPSHA: determines the absolute pressure at the pump impeller.
• Total Dynamic Head: This calculator finds the pressure required at the pump, and the head that the pump must generate.
• Minimum Required Pipe Size: Determine required pipe size based on given flow rate, pipe length, material and maximum allowable pressure loss.
• Pipe Velocity and Diameter: Calculate the velocity of water in a pipe and calculate the diameter of a pipe required for 5 fps pipe velocity.
• Pipeline Pressure Loss: Calculates the pressure or friction loss along a given length of pipeline with a specified inside diameter and the minimum pipe size to limit pressure loss to a specified value.
• Pressure Loss from Laterals with Outlets: Calculates friction loss in a pipe with equally spaced outlets and the minimum pipe size for a pipe with equally spaced outlets.
• Fitting Pressure Loss: The equivalent feet of pipe to add to the pressure loss equation.
• Required System Capacity: Calculate the system capacity (flow rate) required to meet the demands of a field.
• Water Application Rate: Water application rate using the flow rate on an area.
• Water Depth: Depth of water applied to a specified area over the specified time span based on the given flow rate onto the field.
• Total Surge Pressure (Water Hammer): Surge pressure due to a sudden shutting of a valve, or water hitting the end of a pipe.
• Water Supply Design: Estimate of the water flow requirements to replace water lost to evapotranspiration.
