<span>The total equivalent warming impact (TEWI) takes into consideration both the direct and indirect global warming effects of refrigerants.
In addition to the direct impact of the refrigerant (which is conveniently estimated by GWP), any system or process, which requires energy input, indirectly affects the environment. This impact is originated from CO2 emissions from the energy production processes.
TEWI can be calculated using the equation below:
TEWI = direct emissions + indirect emissions = (GWP×L×N)+(Ea×β×n),
where
L – annual leakage rate in the system, kg (3% of refrigerant charge annually),
N – life of the system, years (15 years),
n – system running time, years (based on weather data, 4910 hours),
Ea – energy consumption, kWh per year (modelled for each refrigerant),
β – carbon dioxide emission factor, CO2-eq. emissions per kWh (165 g CO2/kWh).</span>
<span>When prisoners use cigarettes or some other good as money, cigarettes become commodity money and functions as a unit of account.
Commodity money is money where the value comes from a commodity of which it is made. Commodity money is defined as money in which objects have value within themselves. </span>
The quality management concept which must be well-defined at the beginning of the project to help avoid rework and schedule delays is requirements.
<h3>Requirements management</h3>
- Requirements management and quality management go hand in hand. Clear, well-defined requirements lead to less rework and schedule delays.
In conclusion, we can conclude that the correct answer is requirements management.

Answer:
c.could have deposited less money today and still had $5.000 In four years If the account paid a higher rate of interest.
Explanation:
Since the Sam has opened a saving account and paying 3.5% interest compounded annually and after four years the amount of saving account is $5,000
So according to this given data, the Sam should do deposited the less money today and can be $5,000 in four years if the account gives a higher rate of interest
The other options are wrong because in the first case, the same amount in compounding earns higher interest rate as compared to the previous years and other two options will also not give such higher rate of interest
