Mist Nozzle Radius Spacing Calculator

Audit actual consecutive local nozzle center spacings against matched measured radius and caller spacing policy; center-line overlap not full 2D coverage/uniformity, no geodesy or spraying/disease-control recommendation.

Description

Consecutive nozzle-center spacings can be compared with a measured spray radius.

Consecutive nozzle-center spacings can be compared with a measured spray radius. Center-line overlap differs from complete area coverage.^[1]

Enter at least two local x/y pairs, positive matched radius and positive maximum spacing/radius ratio. Preserve station order; return spacings, signed overlaps and strict-overratio pair indices.

When to use Mist Nozzle Radius Spacing Calculator

Use Mist Nozzle Radius Spacing Calculator when you need to evaluate the supplied records under the calculation and evidence rules below. No geodesy, 2 D uniformity, spraying design or disease-control recommendation is provided.

Prepare the measured crop, container, lighting or inventory records requested. Supply verified local catalogs, calibration factors and crop-stage limits; keep units and dates consistent.

How to use Mist Nozzle Radius Spacing Calculator and understand its results

Prepare the measured crop, container, lighting or inventory records requested. Supply verified local catalogs, calibration factors and crop-stage limits; keep units and dates consistent.
Enter observedNozzleLocalPositionsM, callerMeasuredMatchedMistRadiusM, callerMaximumSpacingToRadiusRatio using the field table and calculation rules, then run the tool.
Read observedConsecutiveNozzleSpacingsM, signedConsecutiveOverlapDiametersM, spacingPairsAboveCallerRatio. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
observedNozzleLocalPositionsM	Observed nozzle local positions m	list of list of number	Required
callerMeasuredMatchedMistRadiusM	Caller measured matched mist radius m	number	Required
callerMaximumSpacingToRadiusRatio	Caller maximum spacing to radius ratio	number	Required

Enter at least two local x/y pairs, positive matched radius and positive maximum spacing/radius ratio. Preserve station order; return spacings, signed overlaps and strict-overratio pair indices.

spacing=hypot(Δx,Δy); overlap=2radius−spacing

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
observedConsecutiveNozzleSpacingsM	Observed consecutive nozzle spacings m	list of number
signedConsecutiveOverlapDiametersM	Signed consecutive overlap diameters m	list of number
spacingPairsAboveCallerRatio	Spacing pairs above caller ratio	list of number

Limitations and assumptions

No geodesy, 2 D uniformity, spraying design or disease-control recommendation is provided.

Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Matrices are limited to 128 rows and 128 entries per row. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

Use Grow Light Footprint Coverage Calculator: A coverage grid can inventory which canopy cells receive one or several lamp footprints. Area coverage alone does not describe photon uniformity. For a complementary task, use NFT Flow Rate Per Channel Calculator: NFT channel flow can be measured by collecting discharge for a timed interval. Channels need not receive equal shares of pump flow.
