Furnaces: principles of design and use - ScienceDirect

Jan 01, 1982 · To calculate the heating and cooling times of thin bodies or materials with high diffusivity (e.g. aluminium), the following equation 9, 10 can be used:. θ = {w ρ c p / 3.6 h}. ln {(T f − T 0) / (T f − T θ)} (θ time (h), w = weight of the body (kg/m 2 of exposed surface), ρc p = specific heat (kJ/kg K), and h = heat-transfer coefficient (W/m 2 K).)In the above equation the furnace

Indoor mold - Wikipedia

Because common building materials are capable of sustaining mold growth and mold spores are ubiquitous, mold growth in an indoor environment is typically related to water or moisture exposure and may be caused by incomplete drying of flooring materials (such as concrete). Flooding, leaky roofs, building-maintenance or indoor-plumbing problems can lead to interior mold growth.
