WebNov 7, 2024 · What is thermal diffusivity of water? Thermal diffusivity of water is 0.14558 mm 2 /s. Considering density of air as 997 kg/m 3, thermal conductivity of 0.607 W/m⋅K and specific heat of 4182 J/kg⋅K, the thermal diffusivity is calculated as α = 0.607 / (4182 × 997) = 0.14558 mm²/s. Diffusivity, mass diffusivity or diffusion coefficient is usually written as the proportionality constant between the molar flux due to molecular diffusion and the negative value of the gradient in the concentration of the species. More accurately, the diffusion coefficient times the local concentration is the proportionality constant between the negative value of the mole fraction gradient and the molar flux. This distinction is especially significant in gaseous systems with str… WebNov 27, 2016 · As the chlorine concentration increases, the required water-chlorine contact time ultimately decreases.
