Answer:
Geological and civil engineers sometimes work together, but have very different responsibilities. While geological engineers study the earth's inner and outer surface to evaluate potential mining and infrastructure construction sites, civil engineers design the infrastructure to be built.
Answer:
The ACH is 12/h
Solution:
As per the question:
Area of the space, 
Height of the given space, h = 10 ft
Air flow rate, 
Now, to find the Air Change Rate (ACH):
We calculate the Volume of the given space:
Now, the ACH per min:
= 
Now, ACH per hour:
= 
Answer:
Explanation:
Kindly go through the attachment for the step by step approach to the solution of this question.
Answer:
1). Linear and syndiotactic poly(vinyl chloride); linear and isotactic polystyrene
2). Network phenol-formaldehyde; linear and heavily crosslinked cis-isoprene
3). Linear polyethylene, lightly branched isotactic polypropylene
Explanation:
1). It is very much possible to decide for the two polymers. Here the linear as well as the syndiotactic poly(vinyl chloride) are likely to be crystallize; the side - group phenyl of the polystyrene is more bulkier than CI side group for the poly(vinyl chloride). The syndiotactic as well as the isotactic isomers are likely to crystallize equally.
2). No we cannot decide for the two polymers. Both of them are crosslinked and the network polymers may not crystallize.
3). It is a possible to decide the two polymers. The linear polyethylene is likely to crystallize.
Answer:
Q' = 8 KW.h
Q'=28800 KJ
Explanation:
Given that
Heat Q= 4 KW
time ,t = 2 hours
The amount of energy used in KWh given as
Q ' = Q x t
Q' = 4 x 2 KW.h
Q' = 8 KW.h
We know that
1 h = 60 min = 60 x 60 s = 3600 s
We know that W = 1 J/s
The amount of energy used in KJ given as
Q' = 8 x 3600 = 28800 KJ
Therefore
Q' = 8 KW.h
Q'=28800 KJ
