Here is my current understanding and numbers.
(a) T = [(alpha * Fs) / (epsilon * sigmaSB)]1/4 = [(0.84*1368)/(0.74*5.67x10-8)]1/4 = 406.8K
(b) Here I think I have 2 equations
1) (panel_heat_capacity)*dT = (loss_per_unit_time)* dt
2) (loss_per_unit_time) = 2*epsilon*signma_SB*T^4...
I arrived at the equation from a section in our notes identified as Passive thermal control. In looking at it again I did realize that the formula was incorrect. The formula should be
T = [(alpha * Fs) / (epsilon * sigmaSB)]1/4
derived from:
alpha * A * Fs = epsilon * A *sigmaSB * T4...
Homework Statement
Consider what would happen to the temp of a solar array when a solar spacecraft gets into an eclipse. Distance to the Sun is 1 AU and Fs = 1368 W/m2
Consider an infinitely thin flat panel thermally isolated from the spacecraft . Assume the Specific Heat Capacity is 8.0...
