A sling psychrometer is a device to measure the humidity of air. A porous cloth (the wick) is wrapped around the bulb of a mercury thermometer, which is then whirled around in the air. As the water in the wick evaporates, the temperature of the thermometer bulb drops, and finally stabilizes at the wet-bulb temperature of the air. The dry-bulb temperature is read from a second thermometer mounted on the sling. One summer day, the weather bureau reports a temperature of 33e and a relative humidity of 40%. You wipe the sweat from your forehead and remark to a friend that you'd bet $5 that the report is wrong, and the relative humidity is higher than 80%. He immediately puts a $5 bill on the table, accepting your challenge. You bring out your sling psychrometer, whirl it around, and read a dry-bulb temperature of 35e and a wet-bulb temperature of 27e. Who wins the bet?
September 21, 2016: Chapter 14 Chemical Kinetics: Lecture Summary Chemical Kinetics is the study of chemical reactions in respect to their reaction rates. Chemical Kinetics can provide a lot of insight to medicine and the environment by explaining how long a specific concentration of medicine will be for a continuous amount of time or how long/effective medication will be for the given period of time. Chemical mechanism is the circumstances in which molecules interact (collide) with each other, shedding light on the step by step process in which the reaction takes place. Rate of change in reactions can be correlated to anything else. Reactions Factors that determi
