Answer:
3) the pressure drop across high MERV filters is significant.
Explanation:
MERV (Minimum-Efficiency Reporting Value) is used to measure the efficiency of filter to remove particles. A filter of high MERV can filter smaller particles but this causes an increase in reduced air flow that is an increase in pressure drop. High MERV filters capture more particles causing them to get congested faster and thereby increasing pressure drop.
Excessive pressure drop can cause overheating and lead to damage of the filter. The pressure drop can be reduced by increasing the surface area of the filter.
Answer:
The perceived economic impact of CO2 generated per year by lighting sstem is $8164.67.
Explanation:
The CO2 requirement for the plant is:
Amount of CO2 per year = (2.4 lb / KWh)(300,000 KWh)
Amount of CO2 per year = (720000 lb)(1 ton/ 2204.62 lb)
Amount of CO2 per year = 326.59 ton
The perceived economic impact of CO2 generated per year will then be:
Economic Impact = ($25 / ton)(326.59 ton)
<u>Economic Impact = $8164.67</u>
