A home supplies company decides to produce a reusable moisture absorber product for removing the water content in air in an enclosed space. A reduction in humidity is expected to help inhibit the growth of mold and mildew. As a measure of product performance, the moisture absorber should reduce the relative humidity of air in a closed coat cabinet with dimensions of 2m×1m×1m from 90% to 50% at 25°C . Develop and solve the model for determining the specifications for this product. What is the minimum amount of silica gel to lower the humidity to 50%? What is the required amount of silica gel if the reduction is to be completed in two hours? Much information is available on silica gel in the literature. For example, the maximum moisture content of silica gel, defined as weight of water per unit weight of silica gel, is 0.26. The density of silica gel is 2.64 g/cm3. The diffusion coefficient of moisture in silica gel is 0.37×10−8 m2/s. [ Last edited by 冰点降温 on 2017-3-10 at 09:46 ] |
