UNIT-III. PSYCHROMETRY. 3 INTRODUCTION. The psychrometric is that branch of engineering science which deals with the study of moist air i., dry air mixed. A psychrometer is a device for measuring air humidity. It does so by measuring the temperature difference between a dry thermometer bulb and a wet thermometer.

This is the income of the working 9 to 5 set. It is generally earned from a job via a paycheck. Your ability to earn is based on how long you can work. Earned income is the income you have the least control over. It is determined by your employer, and it can be cut or you can be fired. And if you want to make more money, you have to either find a job or hope that your employer will decide to pay you more. Portfolio income: Most high-paid employees also have some form of portfolio income, usually in the form of a k and various paper assets like mutual funds managed by a financial advisor.
Portfolio income is generally derived from paper assets such as stocks, bonds, and mutual funds. It is the second-highest taxed income, and is moderately hard to build wealth with due to low returns. There are of course big ups and downs that can happen during that time.
Much like earned income, you have little control over your portfolio income. You are at the mercy of the ups and downs of the stock market and the skill of your advisor. Passive income: People with a high financial IQ have an investment strategy that aims to create passive income. Passive income is generally derived from real estate, royalties, and business distributions. If you receive rent from a property, that is passive income. I get royalties from my books.
They are cash-flowing assets that provide passive income. If you own a business that distributes profit to you, that is also passive income. In short, it is income that comes to you whether you are working or not. It is the lowest-taxed income, with many tax benefits, and is the easiest income to build wealth with thanks to its combination of low taxes and potentially infinite returns. Most people start their life out by making ordinary earned income as an employee. The path to building wealth then starts with understanding that there are other types of income and then converting your earned income into the other types of income as efficiently as possible.
Rather, I tell them to pay themselves first and invest that money in cash-flowing assets. In short, convert your pay raise into passive income. The easiest way to do this is to make your investment spend an expense and to make it your most important expense.
Kim and I did this for years, baking our money for investments into our budget expense column. We always found a way to pay our other expenses too, even if it was a little late. In this way we changed our mindset about money and investing. Many people think investing is risky. The investor is the asset or liability. What this means is that your financial knowledge can either be an asset or a liability.
If you want to move from being a risky investor to a good investor, first invest in your financial education. As part of your education—because nothing beats real-life experience—start small with your investments, learn from your mistakes, and then make bigger and bigger investments. You can also play games that simulate investing to build your financial intelligence.
One of my big concerns as a beginning investor was how I would raise money if I found a good deal. Rich dad reminded me that my job was to stay focused on the opportunities in front of me, to be prepared. The hard part was finding a great deal that attracted the money—which is why so many people are ready to give money to a good investor.
It is widely used to illustrate and analyze the characteristics of air-water mixtures in refrigeration, air conditioning processes, and many other processes. Do you know where from the word Psychrometry comes?
Hence, psychrometry used to measure the properties of moist air, their control, the effect on materials, and human comfort. Moisture content in air varies significantly under different conditions like temperature, pressure, altitude, etc. Psychrometric Chart is a graphical representation where all psychrometric parameters can be derived.
Let us take an example when we are inside a car, sometimes we use to see water droplets outside the windows. Where from this water comes? It comes from the surrounding air only. Psychrometry is developed into a psychrometric chart which has a wide function to understand the properties of air-water mixture and calculate the various parameters related to it.
All the psychrometric chart is represented in a Psychrometric which provides the states or condition of the air or water. Would you like to be an expert in HVAC Engineering Design with a best, simple, animated video courses by highly experienced professional!
All the psychrometric chart is represented in a Psychrometric which provides the states or condition of the air at any specific time. It displays the different properties of air:. The Psychrometric terms are described with the explanation. If any of the two psychrometric terms are known, one intersection can be plotted and from that point, other parameters can be determined using the chart.
Psychrometric Terms and definitions are defined below for a better understanding of the basics of air conditioning system:. The amount of pollutants or water vapour varies based on the location. These pollutants, moisture content decrease with the height from the earth surface.
This is the air we breathe and use for air conditioning and ventilation system. Hence, it is necessary to filtrate this air before using it. Normal air consists of water vapour. The quantity of water vapour varies depending on the conditions. If water vapour and all impurities can be able to remove from the normal air, then dry air will be formed. Moist means the presence of water.
When moisture is present in the air, it is called as moist air. Moist air means a mixture of air and water. Air is always consisting of some amount of water vapour. This water vapour depends on pressure and temperature. Now we will take an enclosed space at some specific pressure and temperature and add moisture gradually.
Initially, air consists in the enclosed space absorb the water vapour at the same pressure and temperature. This air is known as unsaturated air that means it can absorb or holds more water vapour. But later, a stage will come when the air will not be able to absorb the moisture anymore.
The extra moisture will be out in the form of dew or fog. The air which can hold the maximum water vapour or moisture at certain pressure and temperature is known as saturated air. Due to heating, the temperature of water gradually increases, and it will reach deg. At deg. C, the addition of heat also is not able to change the temperature of the water. Here, instead of temperature changes, water is started to convert into vapor. When the vapor is able to take the heat without temperature increase, it is known as unsaturated vapor.
Further increase of temperature, entire water will be converted to vapor. This vapor when all the water content will be converted to vapor is known as a saturated vapor. If vapour is further heated, vapour will take the heat at deg. C and there will not be any change in temperature. This steam which is having more heat content than the saturated vapour is called superheated vapour.
The Dry Bulb Temperature is simply the temperature of the ambient air that has no water on its surface. When we talk about the temperature of the air, it is commonly referred to dry bulb temperature. In the Psychrometric chart, Dry-bulb temperature is indicated on the X-axis, and all vertical lines in the chart represent constant temperature lines.
Measurement: You take a thermometer and hold it in the room and note the temperature. The Wet Bulb Temperature is simply the temperature of the air which is associated with moisture. When a normal thermometer is wrapped with a wet cloth, we get wet-bulb temperature.
