Answer:
Sealing agent
Explanation:
Generally, when we have water leaks in almost any building or equipment, we use a sealant. However, this sealant could be of different types depending on the peculiarity of the leakage.
Thus, the correct answer is sealing agent.
Answer:
![\dot Q_{in} = 372.239\,MW](https://tex.z-dn.net/?f=%5Cdot%20Q_%7Bin%7D%20%3D%20372.239%5C%2CMW)
Explanation:
The water enters to the pump as saturated liquid and equation is modelled after the First Law of Thermodynamics:
![w_{in} + h_{in}- h_{out} = 0](https://tex.z-dn.net/?f=w_%7Bin%7D%20%2B%20h_%7Bin%7D-%20h_%7Bout%7D%20%3D%200)
![h_{out} = w_{in}+h_{in}](https://tex.z-dn.net/?f=h_%7Bout%7D%20%3D%20w_%7Bin%7D%2Bh_%7Bin%7D)
![h_{out} = 12\,\frac{kJ}{kg} + 191.81\,\frac{kJ}{kg}](https://tex.z-dn.net/?f=h_%7Bout%7D%20%3D%2012%5C%2C%5Cfrac%7BkJ%7D%7Bkg%7D%20%2B%20191.81%5C%2C%5Cfrac%7BkJ%7D%7Bkg%7D)
![h_{out} = 203.81\,\frac{kJ}{kg}](https://tex.z-dn.net/?f=h_%7Bout%7D%20%3D%20203.81%5C%2C%5Cfrac%7BkJ%7D%7Bkg%7D)
The boiler heats the water to the state of saturated vapor, whose specific enthalpy is:
![h_{out} = 2685.4\,\frac{kJ}{kg}](https://tex.z-dn.net/?f=h_%7Bout%7D%20%3D%202685.4%5C%2C%5Cfrac%7BkJ%7D%7Bkg%7D)
The rate of heat transfer in the boiler is:
![\dot Q_{in} = \left(150\,\frac{kg}{s}\right)\cdot \left(2685.4\,\frac{kJ}{kg}-203.81\,\frac{kJ}{kg} \right)\cdot \left(\frac{1\,MW}{1000\,kW} \right)](https://tex.z-dn.net/?f=%5Cdot%20Q_%7Bin%7D%20%3D%20%5Cleft%28150%5C%2C%5Cfrac%7Bkg%7D%7Bs%7D%5Cright%29%5Ccdot%20%5Cleft%282685.4%5C%2C%5Cfrac%7BkJ%7D%7Bkg%7D-203.81%5C%2C%5Cfrac%7BkJ%7D%7Bkg%7D%20%5Cright%29%5Ccdot%20%5Cleft%28%5Cfrac%7B1%5C%2CMW%7D%7B1000%5C%2CkW%7D%20%5Cright%29)
![\dot Q_{in} = 372.239\,MW](https://tex.z-dn.net/?f=%5Cdot%20Q_%7Bin%7D%20%3D%20372.239%5C%2CMW)
The correct answers are B & C; Chatter Groups and Similar opportunities.
Further Explanation:
Sales representatives can use chatter groups and other similar opportunities to their advantage. This can help them to understand and manage their products that are in direct competition with competitors.
A chatter group can be used to share ideas both privately and publicly. These groups can have more than 30,000 people or just 3 people, it depends on how many are interested in the topic or product. The groups can be made unlisted and by invite only and then you can see with whom you are talking to. Nonmembers can view anything written in the public and archived groups. This is a great way to see how your peers are doing with their product.
