1. The problem statement, all variables and given/known data The solar constant is the amount of energy from the Sun we receive on the Earth during each second on a 1.000 m2 area oriented perpendicular to the direction of the sunlight. The value of the solar constant is about 1.37 kW/m2. Imagine sunlight illuminating an asphalt pavement as indicated in Figure P.63. The ambient temperature is 30°C. What is the equilibrium temperature of the asphalt? Assume the asphalt is a blackbody. Answer is in Celsius* 2. Relevant equations Stefan's Law: dQ/dt = -e(A)([tex]\sigma[/tex])(T^4) where [tex]\sigma[/tex] = 5.670 x 10^-8 W/(m^2 x K^4) Blackbody radiation so the e value should be 1. 3. The attempt at a solution I don't understand how to incorporate the solar constant into the equation. Is the area just 1m^2? I'm lost! =( PLEASE HELP!!! THANK YOU.
