AI-ORGANISED INDEX
construction · air changes per hour, m3/s
The number that decides whether a workshop, a stable or a grain store is workable. See Venting The Workshop.
AI-ORGANISED INDEX
workshop · m3/s
Drying grain needs moving air, not hot air. If the fan is sized for the empty bin it will not cope with a full one. See Storing Grain.
AI-ORGANISED INDEX
meteorology · degrees C
How cold it feels on exposed skin. Important for livestock, workers and young stock.
AI-ORGANISED INDEX
measurement · psi, bar, kPa
Tyre pressures, sprayer pressures, grease guns and air tools. Modern tyres quote bar; old manuals quote psi. 30 psi = 2.07 bar, which is roughly a car tyre.
AI-ORGANISED INDEX
physics · joules (J), kilojoules (kJ)
How much fuel or electricity a heater needs. Water needs far more energy per kilo than steel, which is why a hot water cylinder takes so long.
