Selection scope and sizing decision
Useful for: Fleet planners converting road coverage and refill constraints into a preliminary tank-capacity requirement
Tank sizing is a route and logistics calculation. A larger shell can reduce refills but increases completed mass, axle reactions and the effect of moving liquid on the vehicle.
Application rate is not universal. Surface, dust, weather, speed, nozzle pattern and the desired outcome must come from a defined trial or controlling requirement.
Sizing inputs
Supply these values before a model, body size or working rating is selected:
- 01Area or route length treated per cycle
- 02Effective spray width for each mode
- 03Measured or approved application rate
- 04Refill flow, access and turnaround time
- 05Tank usable-volume and reserve assumptions
- 06Chassis gross and axle mass limits
From sizing inputs to model approval
Size from the operating requirement, test the complete configuration and retain the project records that control the final selection.
- 01Define the target duty
Water sprinkler tank and route-cycle sizing
- 02Quantify sizing inputs
Area or route length treated per cycle; Effective spray width for each mode
- 03Test the complete vehicle
Treatment area and Water demand must both pass.
- 04Approve the selected rating

Selection and sizing matrix
Use every row to test the proposed size. A nominal value is not sufficient when payload, geometry or operating limits conflict.

| Decision factor | What to choose or check | Limit or condition |
|---|---|---|
| Treatment area | Calculate route length multiplied by effective covered width. | Nominal spray width may include overlap or unusable edge coverage. |
| Water demand | Use a documented application rate for the defined condition. | Do not borrow a rate from a different road, climate or nozzle setup. |
| Cycle design | Include travel, spraying, refill and reserve in one timeline. | Tank volume alone does not determine daily productivity. |
| Vehicle limits | Check usable water mass, completed mass and every axle reaction. | Geometric tank capacity cannot override legal or chassis limits. |
Applied calculation
Convert route coverage into a first-pass water volume A route estimate connects road area and an assumed application rate before reserve, refill access and payload are checked.
- 01Covered area24,000 m²
4,000 m × 6 m - 02Base water demand14,400 L
24,000 m² × 0.6 L/m² - 03Configuration checkProject review required
Base demand + approved reserve versus legal payload and refill plan
Decision: The hypothetical route needs 14,400 L before reserve. The result may support one larger load or a smaller tank with a documented refill cycle, subject to axle and operating limits.
Evidence boundary: Illustrative planning values only. Do not use this application rate or spray width without a route trial and the approved vehicle data.
Selection evidence checklist
Ask for evidence that is traceable to the selected model, configuration, vehicle or project scope. A record from another project is context, not verification.
- Route-area and operating-speed worksheet
- Documented application-rate basis
- Usable-volume and refill-cycle calculation
- Completed-vehicle mass and axle-load calculation
Selection and sizing traps
Using shell volume as usable water
Better selection method: Apply the approved fill, reserve and internal-volume basis.
Assuming one application rate for all roads
Better selection method: Measure or approve the rate for each relevant surface and condition.
Ignoring refill flow
Better selection method: Include source flow, hose connection and queue time in the cycle model.
Limitations
- The example method does not prescribe a universal application rate.
- A qualified vehicle calculation and destination rules control final mass and capacity.
- Reject the proposed tank size if gross mass, axle load, stability, fill control or route assumptions remain unresolved.
Evidence scope and technical basis
Each source is limited to what it can support. This makes the evidence chain readable to buyers, search engines and AI systems without turning a general source into a project claim.
Supports: Controls the project-input, quotation, approval and inspection workflow described in this guide.
Does not establish: It does not replace the signed quotation, approved specification, selected OEM documents or unit-linked project records.
Supports: Provides public checklists and worksheets; the signed project documents remain controlling.
Does not establish: It does not replace the signed quotation, approved specification, selected OEM documents or unit-linked project records.
Supports: Defines the relevant product family and published configuration boundaries. Project-specific ratings require the selected OEM documents.
Does not establish: It does not replace the signed quotation, approved specification, selected OEM documents or unit-linked project records.
Supports: Manufacturer primary source supporting pump, PTO, water-level, spray-control, hose, leak and pre-start checks. Its model settings do not rate a KEEYAK project.
Does not establish: It applies to the named manufacturer example and does not establish a KEEYAK model rating or project result.
