Answer:
1) <em>4.41 * 10^-4 kw </em>
<em>2) </em>2.20 * 10^-4 kw
Explanation:
Given data:
Filter = 500 m^3/min
dust velocity = 3g/m^3
bag ; length = 3 m , diameter = 0.13 m
change in pressure = 1 kPa
efficiency = 60%
<u>1) Calculate the Fan power </u>
First :
Calculate the total dust loading = 3 * 500 = 1500 g
To determine the Fan power we will apply the relation
= 
<em>fan power ( </em>
)<em> = 4.41 * 10^-4 kw </em>
<u>2) calculate power drawn </u>
change in P = 6 atm = 6 * 10^5 pa
efficiency compressor = 50%
hence power drawn = 4.41 * 10^-4 kw * 50% = 2.20 * 10^-4 kw
Answer:
Glycogen is the primary energy source for muscle and liver cells.
Explanation:
Glycogen is a readily mobilized storage form of glucose. It is a very large, branched polymer of glucose residues that can be broken down to yield glucose molecules when energy is needed. Most of the glucose residues in glycogen are linked by α-1,4-glycosidic bonds. Branches at about every tenth residue are created by α-1,6-glycosidic bonds.
Glycogen is not as reduced as fatty acids are and consequently not as energy rich. Why do animals store any energy as glycogen? Why not convert all excess fuel into fatty acids? Glycogen is an important fuel reserve for several reasons. The controlled breakdown of glycogen and release of glucose increase the amount of glucose that is available between meals. Hence, glycogen serves as a buffer to maintain blood-glucose levels. Glycogen's role in maintaining blood-glucose levels is especially important because glucose is virtually the only fuel used by the brain, except during prolonged starvation. Moreover, the glucose from glycogen is readily mobilized and is therefore a good source of energy for sudden, strenuous activity. Unlike fatty acids, the released glucose can provide energy in the absence of oxygen and can thus supply energy for anaerobic activity.
Answer:
It has poor tensile strength despite having high compressive strength
Explanation:
Concrete exhibits high compressive strength when used. However, it has very low compressive strength. This is the reason why concrete is normally combined with steel to make a composite building material called reinforced concrete. The steel reinforces concrete hence increasing the tensile strength in RC buildings. The end composite is durable and fireproof. Generally, the main reason why concrete is not use on its own is due to its poor tensile strength.
