Answer:
The required total area is 1.48 m²
Explanation:
Given that,
Latitude = 44+° N
New Mexico,
Latitude= 35+° N
Heat capacity = 4200 J/Kg°C
Temperature = 60°C
Let us assume the input temperature 22°C
Estimate volume of water 100 ltr for 4 person.
We need to calculate the heat
Using formula of heat
Put the value into the formula
...(I)
Let solar radiation for 6 hours/day.
We need to calculate the total energy per unit area
Using formula of energy
Let the efficiency of collector is 50 %
Then, the total energy per unit area will be
....(II)
We need to calculate the required total area
Using equation (I) and (II)
Where, H = heat
E = total energy
Put the value into the formula
Hence, The required total area is 1.48 m²
