These public guides explain calculation steps that connect crop water demand, pipe losses and pump duty. They are published by Tenselo for people preparing or reviewing water-engineering work.
What the worked examples establish
Each example uses stated, hypothetical inputs. The arithmetic and unit conversions are checked independently of the Tenselo application. Rounded figures are for readability; calculations retain precision before rounding. These examples are not customer projects, field trials or evidence of specialist approval.
Where the methods come from
- Pump duty and power: the energy balance and head relationship, with US Department of Energy and EPA references.
- Pipe head loss: velocity, Darcy–Weisbach and fitting-loss relationships, with the EPA EPANET manual reference.
- Crop demand and run time: FAO crop-coefficient and gross irrigation depth relationships, with the assumed efficiency stated.
Additional irrigation examples
The centre-pivot example uses circle geometry, a daily water balance and area-based flow allocation. It does not select a nozzle package or machine. The drip-lateral example sums segment losses with a deliberately fixed Darcy factor to illustrate declining flow. Real designs require a suitable friction method and manufacturer emitter data.
What requires project-specific review
Verify site levels, water conditions, operating cases, manufacturer curves, exact product dimensions and current standards applicable to the project. A general method reference does not establish Australian or New Zealand regulatory compliance. A competent person must assess the complete design before procurement or construction.
Public guides and the Tenselo application
The website provides product information and static educational content. Project calculator execution is in the separate, account-based Tenselo application. New accounts require approval; pricing and subscription availability are described separately.
