Math & Numbers

Convert dynamic (absolute) viscosity between Pa·s (pascal-second, SI base, = N·s/m² = kg/(m·s)), cP (centipoise, 1 cP = 0.001 Pa·s), and lbf·s/ft² (imperial, 1 = 47.88025898 Pa·s). Converts via Pa·s to the target unit and also lists the equivalent value in all three units for reference. Reference values: water 20°C ≈ 1.002 cP, glycerol 20°C ≈ 1412 cP, air 20°C ≈ 0.0181 cP.

Compute the air dew-point temperature from dry-bulb temperature and a humidity reading using the Magnus saturation-pressure equation: P_ws(T) = 0.6108·exp(17.27·T/(T+237.3)), P_w = φ·P_ws, T_dp = 237.3·ln(P_w/0.6108) / (17.27 − ln(P_w/0.6108)). Also returns the saturation vapour pressure P_ws, actual partial pressure P_w, and absolute humidity ρ_v (kg/m³). Three input modes: relative humidity φ (natural ventilated), August natural-ventilated wet-bulb T_w, or aspirated (Assmann) wet-bulb T_wa. Temperature in °C/K/°F; all reported temperatures are in the selected Temperature Unit.
