Re: Time required to heat half kg of water using thermal solar

The ambient temp is 110 F.

At 20 mph the air side heat transfer coefficient is 20 watts/m^2-C.

Heat Input = Coefficient * Area * Temp. Diff. * Time
= 20 X 0.055742 X 43.32 X T
= 48.2948 X T

Heat Required

Latent Heat of Ice= 80 Cal/g
1 Pint of water= 473.176 g
Heat required= 80 X 473.176 Cal
= 44.058 Watt-hr

Time= 44.058/48.2948
0.9121 Hr
or 54 Minutes.

Hope we stop at this.

BTW Ben that was good concept elaboration. Thx.

Even if the observation is clear?
