A little more
understanding.
Fifteen working tools for atmospheric optics, droplet physics, energy accounting and experimental design. Change an input. Inspect the assumptions. Keep the result.
Optics
Visibility & extinction
Turn measured transmission into extinction and a derived optical range.
OpticsWater, size & light
Explore how equal water content can produce very different extinction.
OpticsDroplet spectrum explorer
Compare number, water mass and approximate extinction across wet droplet sizes.
Engineering
Flow & collector area
Find face velocity and idealized fan input for a supplied area.
EngineeringWhole-system energy ledger
Keep air throughput, recovered water and electricity in the same ledger.
EngineeringResidence & reset time
Estimate a transit time and an ideal mixed-volume washout.
Electrostatics
Charged droplet drift
Compare ideal electrical drift and gravitational settling in still air.
ElectrostaticsRayleigh charge scale
Calculate the ideal charge scale for an isolated conducting droplet.
ElectrostaticsElectric-field energy
Estimate the energy density and storage of an ideal uniform field.
Atmosphere
Humidity & dew point
Translate temperature and relative humidity into a liquid-water dew point.
AtmosphereFog evaporation energy
Estimate the latent heat needed to evaporate airborne liquid water.
Experiments
Paired fog-trial analysis
Analyze transit-aligned upstream/downstream means across independent days.
ExperimentsIndependent-day planning
Explore how precision and systematic bias affect the approximate workload.
ExperimentsBalanced trial schedule
Export a reproducible, balanced C/D order across preparation days.
ExperimentsMeasurement bias budget
Translate component bounds into a worst-case log-ratio allowance.
