And as if by magic I have an answer that looks reasonable, I can't thank you enough for your help CHET!

Ok I will do tomorrow! Thanks again Leo

Radiative heat flux as 17470 & convective heat flux as 2600 and I've tried both ways with the temperatures because I had it in mind from one of your earlier posts. Thanks for all your help and comments CHET I can see I'm probably getting to be a pain now. Is the correct equation for the...

Scratch what I said about cracking it; I get some ginormous minus number!

That's great thankyou! I see why the areas aren't needed now! -Leo

Sorry for asking so many questions but how exactly did you go about calculating the convective heat flux? And with regards to the radiative flux; maybe -I wasn't sure which temperature was which in the equation -Leo. Yeah, I'm a mere mortal, not a physics God!

Don't be silly -you're the one helping the needy after all! I'll check in the morning, it's late where I am but I'll be sure to let you know how I get on. And thank you very much! -Leo

I can't see them on the iPad app

Ah, yeah true

Sorry for the calcs, I can't because they don't have many symbolic characters (or at least I can't find them) but thank you so much for trying to read my scrawl!

I've broken physics or done the calcs wrong -my final temperature is cooler than the ambient temperature! (5.7) -more likely the latter. Any help would be much appreciated! -Leo

I don't know, that's why I asked.

Am I missing anything or are the only equations to use Fourier's law, Stefan-Boltzmann Law & convective heat flux?
