Answer:
hello some parts of your question is missing attached below is the missing part ( the required fig and table )
answer : The solar collector surface area = 7133 m^2
Explanation:
Given data :
Rate of energy input to the collectors from solar radiation = 0.3 kW/m^2
percentage of solar power absorbed by refrigerant = 60%
Determine the solar collector surface area
The solar collector surface area = 7133 m^2
attached below is a detailed solution of the problem
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)
Answer: (a) +/- 7.5° (b) +/- 3.75°
Explanation:
See attachment
A formal indication from a state, on letterhead, or an official state form, which shows that an applicant has valid driving privileges and is clear to apply for a Colorado driver's license is called a clearance.
<h3>What is a learner's license?</h3>
A learner's license is also referred to as learner's permit and it can be defined as a category of driver's license that is issued to an individual who is learning how to drive an automobile vehicle (car).
<h3>What is a license?</h3>
A license is also referred to as a certificate and it can be defined as an authorization that is typically issued by state governments to a driver, so as to avail him or her the legal ability to physically driver in all the states across a country.
In this scenario, we can infer and logically deduce that a clearance is a formal indication from a state which shows and affirms that an applicant has valid driving privileges, and is permitted to apply for a Colorado driver's license.
