<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>
Answer:
in food they provide day-to-day nutrients that the body needs in order to function
Explanation:
Answer:
current ratio = 3. 80 times
Acid-test ratio = 2 times
Explanation:
<em>The current ratio is the sum of sum of current assets divided by current liabilities. It is used ti measures the the ability of Airline Accessories to meet its short -term obligation falling due within a year</em>
Current ratio = 96 + 88 + 12/ (86 + 29)
= 3. 80 : 1
Acid test ratio also measures liquidity but with adjustment for risky current assets i.e inventory.
Acid test ratio = current asset - inventory/ Current liabilities
= (96 + 88 + 12)/(86+29)
=2 : 1
Answer: c. A-One or Best.
Explanation:
Best Collection Company are the ones who cause the accident and so they can be held liable and have to compensate Carl for injuries and harm caused.
Best however, was acting as an agent on behalf of A-One Auto Sales so A-One can be held liable as well for the incident. Carl can therefore also be compensated by A-One as well.
Carl cannot be compensated by both for the same incident as this amounts to double compensation but can be compensated by either one of them.
