1. Solar Collector Problem:
From the diameter of the sun and the earth and the mean distance of sun from earth, estimate (a) the
amount of energy emitted from the sun, (b) the amount of energy received by the earth, and (c) the solar
constant for a sun temperature of 5700K. If the distance of Planet-Y from the sun is 7.0 astronomical
unit, estimate, (c) the solar constant for Planet-Y for a sun temperature of 5700K. (Stefan-Boltzmann
constant, o = 5.67 x 10-8 W/m2-K4). Diameter of the sun = 1,392,000 km; DiaPlanet-y = 340,800 km;
Mean distance of the sun from the earth = 149,600,000 km
