A car wash requires 1200 US gallons of warm water each day heated from 50 degrees
Fahrenheit to 110 degrees Fahrenheit. How large a solar collector would be needed?
Assume the average incident solar energy flux is 1100 BTU per square foot for 24
hours, and the collector efficiency is 60%.
Convert this problem to SI and solve it.

I've done most of this using the equation$$E=mC _{p}DeltaT$$ and have found E = 9.7 x 10^9 J

u r near 2 the ans...

anonymous · Answer

yes, I'm just confused about how to answer, "how large a solar capacitor"

anonymous · Answer

no u r there!! u know the value' put there!

anonymous · Answer

solve it!!

good luck !! :)

Well... I have the average incident solar energy flux as 144Wm$$^{-2}$$ but I'm confused what to do with these figures to give me the size of the capacitor???
