Question

surface area of 2.5 metre square area receives 2100 energy in 10 minutes calculate the value of solar constant​

Answer 1

Answer:

At the upper reaches of our atmosphere, the energy density of solar radiation is approximately 1,368 W/m2 (watts per square meter). At the Earth's surface, the energy density is reduced to approximately 1,000 W/m2 for a surface perpendicular to the Sun's rays at sea level on a clear day.

Answer 2

Answer:

area = 2.5 m²

energy = 2100

time = 10 min

now solar constant is given by = energy/ area × time

solar constant = 2100/2.5×10

"". "". = 2100/25

solar constant = 84 w/m²
