Pump Sizing Calculator
Estimate total dynamic head, pipe size and matched pump for your system.
Recommended Pump Specification
How this was calculated:
Pipe sizing follows standard velocity guidelines (1.0–1.5 m/s) referenced from FAO/USDA irrigation design practice.
Frequently Asked Questions
What is Total Dynamic Head (TDH) and why does it matter?
Total Dynamic Head (TDH) is the total equivalent height that a pump must lift water, combining static lift, friction loss in pipes, and pressure required at the emitters. Accurate TDH calculation is critical because it determines the pump's power rating. Oversizing leads to high energy costs, while undersizing causes insufficient pressure and poor irrigation performance. The LORAVEDA Pump Sizing Calculator automatically accounts for these variables to ensure you get the perfect match.
How do I calculate the required flow rate for my farm?
The required flow rate is calculated by multiplying the total number of emitters (or sprinklers) by their specific water discharge. Our calculator aggregates these inputs based on your field area and irrigation system layout, instantly providing the minimum flow rate (m³/h) your pump must deliver to sustain efficient, uniform irrigation across the entire plot.
