the perspective of the co-effects of micro-macro mixing and mass transfer theory. At low multiple impeller stirring rotation speed‚ the level of supersaturation had a wide variety of different local areas in the interface region between particle and agitation medium. Meanwhile‚ when the multiple impeller stirring rotation speed was excessively high‚ the micro-macro mixing was significantly increased‚ and the CO2 transfer coefficient was additionally intensified into the system. Higher multiple impeller

The purpose of the experiment was to learn about the thermoregulation‚ and more specifically ectotherms. The experiment was designed to learn how ectotherms rely on external temperature for heat. The hypothesis of the experiment was whether there was temperature variance between two habitats‚ and how it affects the ectotherms. To test the hypothesis‚ we used I-buttons to record the temperature and ANOVA test for p-value. The results supported the hypothesis. Introduction: Thermoregulation is a

The entropy of the system remains in constant. Entropy is a type of energy (like heat‚ work‚ and enthalpy) and is by definition energy which is lost in a process. If a process is both reversible and adiabatic‚ then it is an isentropic process. An isentropic process is an idealisation of the expansion process which assumes there is no heat transfer between the system and its surroundings (No heat transfer is called "adiabatic"). Note that energy can be exchanged with

Global Heat Exchangers Inc. Deirdre Collins‚ buyer-expediter for Global Heat Exchangers Inc. (GHE)‚ was faced with an important purchasing decision. A large new client had just signed for a substantial order‚ and production was scheduled to begin in a couple of days. Unfortunately‚ the original pricing of the project was now being threatened because a GHE supplier had just raised its prices considerably. Company Information. Global Heat Exchangers Inc. (GHE) was established in 1920 and had since

MECH 8250 – Building Systems Module 1 - Heating Load Calculations Module 1 Heating Load Calculations The amount of heat is required for the building heating system to maintain a balance of the building heat loss. The amount of heat and moisture are gained from the building internal and external heat sources that is required to be removed by the building cooling system. Both heating and cooling loads form the basis in designing the HVAC systems for the building and occupied spaces to achieve both

collected. The cooling system design has been refined as a result of the testing carried out in this project. The test data has been analyzed to identify heat rejection requirements‚ optimal engine operating temperature‚ and other important design parameters. It has been found that the cooling system used in the race car must reject 9500 Watts of heat energy‚ and should aim to maintain an operating temperature of 85°C. The 2007 cooling system promises to be successful and an improvement over last years

measure the comfort level in order to avoid over consumption of energy used to heat or cool the buildings. In 1970 Fanger laid out the foundations of this measure using his PMV-PPD model; which is based on heat balance equation. However this model considers human body as a passive object and does not give an accurate result when used in tropical countries and other countries like Spain. Due to the wrong predictions of static heat balance model‚ a more dynamic approach to thermal comfort is needed. This

Introduction I am investigating factors that affect heat loss from a body. All athletes become hot during exercise and need to be aware of how fast their bodies will cool down after the exercise. In extreme conditions the continued drop of body temperature may cause hypothermia. Hypothermia is caused by the core body temperature dropping below 35degrees. This is why it is important to how quickly the body loses heat and what affects it. Heat is lost from the body in 3 different ways conduction
