Sprayer Calibration Calculator & Spray Drone Coverage
Wired White v2 Calculate nozzle flow from pressure, spray application rate and tank loads. Plan a spray drone field path, battery swaps and effective hectares per hour.
Agriculture
Farm and field engineering by the numbers: drip irrigation laterals and their uniformity, FAO-56 irrigation scheduling from evapotranspiration and soil water, NPK fertilizer blends and rates, and grain bin capacity, aeration and drying time. Each calc shows its method and published sources.
Wired White v2 
Hydroponic Nutrient Calculator: Salt Weights, ppm and EC
Wired White v1 Calculate macronutrient salt weights, compare target and achieved elemental ppm, plan separate A/B stocks, and estimate EC from the dissolved ions.
Greenhouse Heat Loss & Ventilation Calculator: 24-Hour Climate
Wired White v1 Model greenhouse temperature over 24 hours with solar gain, shade, fan ventilation, evaporative pads and heating. Compare heat loss and cooling capacity.
Drip Irrigation Calculator: Lateral Length & Uniformity
Wired White v1 Calculate pressure and emitter flow along a sloping drip lateral. Find the maximum line length that meets emission uniformity and operating-pressure limits.
Fertilizer Calculator: NPK Blend and Rate Planner
Wired White v1 Blend two or three mineral fertilizers to match an N–P₂O₅–K₂O target. Compare cost, excess nutrients, nitrogen limits and split application doses.
FAO-56 Irrigation Scheduler: ET, Soil Water and Run Time
Wired White v1 Calculate grass-reference evapotranspiration, crop water use, soil depletion and sprinkler or drip run time. Explore a daily FAO-56 water balance across a growing season.
Grain Bin Capacity, Aeration Fan and Drying Time
Wired White v1 Estimate grain bin capacity with a peaked cone and packing. Match corn resistance to a fan curve, calculate water shrink, and explore a rising drying front.
