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

An Arrangement to Ensure Optimum Temperature of Traffic Police Booth K. Augustine Babu and P. Sherjin Department of Mechanical Engineering‚ Sri Ramakrishna Institute of Technology‚ Coimbatore‚ Tamil Nadu‚ India Abstract The temperature of the traffic police booth is found to be at an elevated level during hot sunny days‚ which may cause discomfort to the person who is standing under it. Lowering this high inside temperature of the booth is the central theme of this work. Semi-conductor

Paragraph 1 In this paragraph‚ the structural and chemistry differences between quartz‚ α-FePO4 and β-FePO4 will be discussed. Quartz do have some similarities with the other 2 components. The structure of quartz‚ similarly depends on the temperature of the environment. Quartz can exist as an alpha or beta form. This is one similarity between the 3. The difference between α-FePO4 and β-FePO4‚ is that α-FePO4 is the most common form of existence for FePO4 and is structurally similar to the alpha

The effect of elevated temperatures on the coated carbon TRC tensile strength is shown in Figure 10. The mean results of strength‚ strain and elastic modulus (at 7 days of age + heating and cooling process) are given in Table 4. The values‚ as well as the standard deviations‚ refer to three TRC test specimens. As well as in the uncoated carbon TRC‚ a strain-hardening behavior is clearly observed in the stress-strain curves up to 400°C. Although not impregnated by matrix‚ the coated carbon TRC presented

However in example 6‚ the H2O molecule given in the question is in the liquid state. Thus liquid water has to be converted into steam first. To convert 2 moles of liquid water into 2 moles of steam‚ an additional 82 kJ of energy is required. By using Hess’s Law‚ ΔH + 2(799) + 2(41) + 4(460) = 4(410) + (496) ΔH = -888 kJ mol-1 Alternative: energy absorbed during bond breaking = 4(410) + 2(496) = 2632 kJ energy released during bond forming = 2(799) + 4(460) + 2(41)

2.2 Peltier Thermoelectric cooler (TEC) Peltier thermoelectric heat pump is a popular thermoelectric energy conversion module that applies the Peltier effect‚ transferring heat energy from one side of the device to the other side. Peltier effect occurs when two different semiconductor materials (n-type and p-type) are joined together with electric current passing through its junction. Therefore‚ the junction could either be cooled or heated [28]. The Peltier TEC device can behave like a temperature

Omar Nunez Period 8 February 7‚ 2013 Mrs. Dube Endothermic vs. Exothermic Reactions Brr! Exclaimed a kid who touched citric acid and baking soda combined. When those two mix‚ it creates a cold endothermic reaction. An exothermic reaction is a reaction that releases energy in the form of an increase in temperature. Endothermic reactions are reactions that absorb energy and cools down surroundings. (Many examples give away exo and endothermic reactions). So listen up! To begin with‚ a chemical

1. Objective The aim of this laboratory experiment is to analyse the rate of heat transfer losses through convection and radiation separately from a cylindrical glass rod suspended in a pressure vessel. The variation of the dimensionless quantities; Nusselt number‚ Prandtl number and Grashof Number‚ with Pressure are to be analysed graphically as well. The experimental graph of log10(Nu) vs log10(Gr.Pr) should be plotted and analysed against the graph of the empirical equations. 2. Introduction:
