Question

Need some guidance on this one.

1. Given the solar flux at Earth is 1370 W per meter squared

Calculate the flux at

a) Mars and

b) Jupiter

2. Calculate the value cosO cosO/pie(r^2) between the center of the radiator and points A and B and multiply this value by the area of the radiator.

Two answers stem from this, A times the area of the radiator and B times the area of the radiator. The picture isn’t that good. The radiator is perpendicular to the solar array. If you put the solar array flat on a table, the radiator would be perpendicular, with the lower edge touching the table, as shown below. B is in the center of the solar array, A is on the corner. The solar array is wider than the radiator (150 cm vs. 100 cm)

Explanation / Answer

1) For Earth,

Distance from Sun = 1 AU

Solar Flux = 1370 W/m^2

Then For Mars:

Distance from Sun = 1.5 AU

Solar Flux = 1370*(1/1.5^2) = 608.9 W/m^2

Then For Jupiter:

Distance from Sun = 5.2 AU

Solar Flux = 1370*(1/5.2^2) = 50.7 W/m^2

2) Statement is not much clear
