Growth Formulas and Relation to Welfare

In macroeconomics there are two key questions: first, how to measure (real) output growth? and second, how is growth connected to wellbeing?

As for the first question, there are three ways to measure real GDP growth. It starts with the definition of a percentage difference between two numbers, say
x1 compared to x0. When there is only one good (e.g. apples) there are no prices to worry about for the calculation. But for the economy as a whole, we need
prices to be able to add up quantities (of apples, bananas, and everything else) in dollar terms. So for real GDP growth, which holds prices constant on a
given base year to control for inflation, then the trick is to apply those prices before, during, and after that base year in order to calculate the total
dollar value of all goods and services produced and track growth that is not affected by inflation.

In this exercise you will work out the connection between the three ways to measure GDP growth: A) As a percentage change holding prices constant. B)
Expressing growth in terms of a common item (converting everything into a particular good (e.g. apples). And C) as the weighted average of the growth in each
of the goods weighted by their corresponding expenditure shares.

The second question in macroeconomics refers to a mapping from goods and services to subjective well-being. That is, why do we care about economic growth,
after all?

idea behind this process is to determine the water and oil initial saturation.
Similarly, during the same week I also get a chance to work in MICP (mercury injection and capillary pressure), this task deal with high and low pressure (figure 2, appendix 2) also using the Archimedes principle which state that the body immersed in a fluid and buoyed up by a force. In order to get the whole volume of the sample using mercury, this process is used with a small size of samples.

Nevertheless, CT scan also was one of the tasks that assigned to me while working in SCAL section. The task include making videos of core sample, analyze the fractures, and the flow of fluids.
Another key thing to remember is flush cleaning which is also a part of SCAL section and one of the highlights task given to me during the internship. The flush cleaning is about using different solvents such as methanol (‘CH’_3 OH) and toluene ( C_7 H_8) to dissolve many organic compounds.
This process contain of two parts first to clean the sample from hydrocarbons using toluene and methanol, when the solvent is discolor that mean the sample is free of hydrocarbons, second part is to check the present

Of any salts in the sample by adding a drops of Silver Nitrate (‘AgNO’_3) if there is precipitation the sample is not clean properly.
For week four of this training another task was arranged for me, dean stark is one of the processes I worked on in fourth week. This process mainly talk about the percentage of oil and water present in the sample and how to extract it (figure 3, appendix 2).
Dean stark is one of the devices used specially to extract oil and water from samples. The solvent that is used for this process is pure toluene that has a boiling point of 110 C ”.

8.

First the toluene is hated up in certain temperature that cause the water inside the sample to evaporate after that the toluene and water vapour both condense in water cooler and the toluene in its liquid state go back into the sample to dissolve the oil inside the sample and the water in the cooler is distilled, secondly the sample will be free of water after the process is completed.
