and latent heat. We shall now see how the air behaves when it is subjected to changes in temperature and humidity to suit the various applications for which the air conditioning is meant. The behavior of the air can be studied very conveniently and accurately by using a psychrometric chart...
How to find psychrometric constant? The ratio of specific heat (Cp) of moist air at constant pressure to latent heat (Lv) of vaporization of water. This constant has a value ofγ = Cp/Lv≅ 0.4 (gwater/kgair) K-1. What is a psychrometric chart?
Thus, warm air has a greater capacity for water vapor than cold air. If saturation vapor pressure is reached in air or in a gas mixture, the introduction of additional water vapor requires that an equal amount condenses out of the gas as a liquid or a solid. A psychrometric chart shows...

As nouns the difference between diagram and chart is that diagram is a plan, drawing, sketch or outline to show how something works, or show the relationships between the parts of a whole while chart is...
The concept behind a wet bulb thermometer is simple, but keep in mind that, to measure relative humidity, it has to be used in conjunction with a dry bulb thermometer. The dry bulb temperature is basically the temperature of the air, but the wet bulb temperature is affected by the evaporat...
The first thing to know here is that the velocity of the air matters. When the air moves quickly through the coil, it cools down to a certain point. If you now slow that air down so that each little bit of it spends more time in contact with the coil, it gets cooler. And that ...

What is the chemical potential in terms of grand function? Enthalpy: Enthalpy, as used in thermodynamics, is the movement of heat energy that a chemical process can either release or absorb from its surroundings. The chemical potential of the reaction tell...
Using the psychrometric chart, determine (a) the relative humidity, (b) the Late on an autumn day, the relative humidity is 48.0% and the temperature is 20.0 degrees Celsius. What will the relative humidity be that evening when the temperature has dropped ...
