Answer:
The exit temperature of hot water =200.005°F
Explanation:
Given that
Volume flow rate of water = 20 gpm ⇒
Volume flow rate of water =
inlet temperature of water = 200°F
Heating load = 92.000 Btu/hr ⇒ Heating load= 0.0269 KW
We know that mass flow rate is given as
So mass flow rate of water = 1000 x 0.00126 Kg/s
mass flow rate of water= 1.26 Kg/s
Now by balancing heat
Heating load =
=200.005°F
So the exit temperature of hot water =200.005°F
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.
