The air has a dry ball temperature of 32 °C and a wet bulb temperature of 24 °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 3.0 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)
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
