ETCO2 Monitoring What is EtCO2 EtCO2 or End Tidal Carbon Dioxide is the partial pressure or the maximal concentration of Carbon Dioxide at the end of an exhaled breath‚ which is expressed as percentage of CO2 or mmHg. The normal values are 5% to 6% CO2‚ which is equivalent to 35-45 mmHg. The term ‘capnometry’ is used to refer the measurement and display of concentration of EtCO2. Another term associated with this parameter is ‘capnography’‚ which refers to the display of a calibrated and a visual

endothermic reactions occur. Entropy Entropy (S) is a measure of the disorder (or chaos or randomness) of a system. The entropy of the universe is increasing. Things become more stable when they become more disorderd (Second Law of Thermodynamics for the Physicists!) Think of a typical teenage bedroom: Question Can you think of other everyday examples where there is a high entropy? See powerpoint slides Entropy measures how much the energy of motion of the particles

Determination of Heat Capacity In this experiment‚ an improvised calorimeter was used to determine the heat capacity. The calorimeter weighed 4.47 grams prior to the addition of water. Tap water‚ 40 mL to be exact‚ was added to the calorimeter which increased the weight to 43.87 grams. The water was measured using

Put another way‚ according to the law of energy conservation the total heat energy lost by the metal is the total heat energy gained by the water and container: Qlost Qmetal Qgained Qwater Qcontainer mmCm Tm mwCw Tw mcCc Tc In thermodynamics (which we will start in a week) a negative sign would be used on the Qmetal term to maintain our sign convention for heat; we set the hot side to be negative because energy is

hour course‚ the open‚ simple Brayton Cycle used for stationary power generation is considered providing thrust instead of power output. In order to keep the scope of the thrust analysis simple‚ the working fluid exiting gas turbine expands to the atmospheric conditions -- final working fluid exit pressure is equal to the ambient pressure. The Brayton Cycle thermal efficiency is presented only for the air as the working fluid. The thermal efficiency derivation is presented with a simple mathematical

DEFINITION OF HEAT TRANSFER | Heat transfer is energy in transit due to temperature difference . Whenever there exists a temperature difference in a medium or between media‚ heat transfer must occur. The basic requirement for heat transfer is the presence of temperature difference . There can be no net heat transfer between two mediums that are at the same temperature. The temperature difference is the driving force for heat transfer‚ just as the voltage difference is the driving force for electric
