The air has a dry ball temperature of 40 ° C and a wet bulb temperature of 20 ° C is heated in a heater so that the temperature of the dry ball increases to 90 ° C. The air is then passed through the corn kernels pile to dry. air that comes out of the pile of corn kernels to dry. The air that exits the corn kernels is at a dry bulb temperature of 60 ° C. then this air is passed to the dehumidifier to reduce its RH to 10%. Draw the course of the process of changing the air on the psychometric diagram. The airflow rate through the corn kernels pile and dehumidifier was 6.0 m / s and the pile cross-sectional diameter was 0.5 m. a. determine the amount of water lost from the pile of corn kernels (in grams of water / second) b. determine the amount of water lost from the air when passing through the dehumidifier (in grams of water / second)
Energy transfer
The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.
Molar Specific Heat
Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)
Thermal Properties of Matter
Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which is transferred between the two systems or in between the systems and their surrounding by the virtue of difference in temperature. Calorimetry is that branch of science which helps in measuring the changes which are taking place in the heat energy of a given body.
