Solved: You would like to put a solar hot water system on
Chapter 19, Problem 19.103(choose chapter or problem)
You would like to put a solar hot water system on your roof, but youre not sure its feasible. A reference book on solar energy shows that the ground-level solar intensity in your city is 800 W/m2 for at least 5 hours a day throughout most of the year. Assuming that a completely black collector plate loses energy only by radiation, and that the air temperature is 20C, what is the equilibrium temperature of a collector plate directly facing the sun? Note that while a plate has two sides, only the side facing the sun will radiate because the opposite side will be well insulated.
