Vapour diffusion retarders and air barriers are designed to keep a building healthy and strong by preventing moisture infiltration, neutralizing differences in air pressure and preventing heat exchange. Each performs a different function although some materials serve as both an air barrier and a vapour retarder. The Difference Between Air Barriers and Vapour Retarders Architects, engineers and others involved in building science research and construction examine the way that both air and…
A soil moisture sensor is an integral aspect of the various precise irrigation techniques. This project focuses soil moisture sensor which can be implemented in a large array spreading throughout an irrigated field. Soil conductivity depends on the moisture content around the probes. This is particularly useful for monitoring moisture levels around roots of crops planted in an organized manner. The network architecture allows real time monitoring. A microcontroller is used to scan the array of…
Excess moisture encourages mold growth, especially when it’s located in dark and humid areas with lots of organic material. There are several ways you can control or remove moisture from your property. Listed below are a few moisture prevention methods you can apply. Basement Insulation and Crawl Space Encapsulation Having your basement insulated and your crawl space encapsulated…
Where M.R is the moisture loss ratio, M_0 is the initial moisture content, M_t is the moisture content at time t, M_e is the equilibrium moisture content, t is time (minutes), and a, b, c, and k are constants. For the effectiveness of diffusivity, Fick’s equation was used (5) to estimate the dehydration kinetic of different osmotic conditions. M.R=((M_t-M_e)/(M_0-M_e ))=〖8/π^2 e〗^((-(π^2 Dt)/(4L^2 )) ) …(5) Where D is the effective diffusivity, and L is the length of the (cubical) sample.…
be able to breathe easier, and not have to worry about contaminants. The reservoir for the dehumidifier holds up to 70 pints of moisture a day, allowing you to spend less time dumping the moisture out. If you place it by a drain, you can start it up, and let it work it’s magic without dumping the reservoir. The humidity control allows you to set the amount of moisture in any given room, allowing for a lot or none at all. The controls are electronic, making it easier to set the dial to your…
Moisturising and retaining hair moisture Most people are usually surprised that my hair feels “soft” to the touch. I suppose the expectation is that it will be dry or “skirpoto” as people usually refer to natural hair. My hair is soft, because it is well moisturised – moisture retention is key to growing and managing African hair. However, this was not always the case, I struggled to keep my hair moisturised, in the beginning. I have 4c high porosity so my hair losses moisture easily and it…
amount. Most upheavals only affect parts of the foundation while the rest remains stationary. This differential movement is what causes the damage. The Cause of Upheavals Large areas of Texas have clay soils that are unusually unstable when their moisture content changes. The soil shrinks when it…
want to consider purchasing gun safe dehumidifiers. What Are Gun Safe Dehumidifiers? A dehumidifier is a device that works by removing moisture from the air. They are great in a home that may be closed up for a while or homes that are in naturally damp areas of the world. They can cut down on allergens and dust, mold and mildew, and…
Silica gel is the little packages inside of products that were listed . Silica gel is to keep moisture out of those objects. Silica gel keeps the moisture from the product so it can stay dry. Silica gel can be in numerous places they can be even bought online. What does silica gel do Little packs of silica are(desiccant) means is a drying agent something that drys objects and absorbs the the moisture. Silica gel was made to absorb and hold moist, And prevent condensation, .Also to…
