This article will guide you about how to calculate specific heat and heat capacity of soil. Specific Heat: Specific heat may be defined as the amount of heat required to raise the temperature of one gram of a substance by 1°C. The specific heat of dry soil (0.2 cal/g) is only about one-fifth that of water (1 cal/g). Hence, moist [...]
After reading this article you will learn about:- 1. Meaning of Mechanical Analysis 2. Process of Mechanical Analysis 3. Principles 4. Stokes's Law 5. Practical Implications. Meaning of Mechanical Analysis: The mineral component constitutes the largest volume of soil mass and plays a vital role in determining most of the physical properties of soil. This mineral portion consists of particles [...]
After reading this article you will learn about the relationship between thermal conductivity and diffusivity. In thermal conductivity and diffusivity the movement of heat in the soil will be considered. Because it is found that much of the solar radiation is dissipated into the atmosphere. Part of it, however, moves slowly through the soil profile by conduction process. Once the [...]
