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.(adsbygoogle = window.adsbygoogle || []).push({});

^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?
