Solar energy collector formula

  1. Jan 25, 2006 #1
    I'm stuck on a formula I'm using to design a solar water heater at uni (and no, I'm not a physics student, otherwise I'd probably be kicking myself its such a stupid question) and I understand the theory behind it, I just can't work out what the Qs stands for.

    ^T=Qs / mC

    where ^T= change in water temp,
    m= water flow rate in m/kg,
    and C= specific heat of the water

    I've tried rearranging the formula but it was never my strong point at A level, and the Qs appears to be representing energy, but of what I'm not sure.

    Any ideas?

    Q = mc[itex]\Delta[/itex]T, where Q would heat (thermal energy/enthalpy), m = mass, c = specific heat, and [itex]\Delta[/itex]T = differential temperature.

    Perhaps in ^T=Qs / mC

    Q = energy flux (energy/ unit area) and s = surface area, so that Qs = energy.

    Thank you!!

    Now I feel a bit stupid, I knew Q=mc^T from my Physics a couple of years ago, but didnt even see it in this one:rolleyes:

    Thanks again for pointing it out.
