Cheers for the reply and I realise now what I was asking was a bit 'broad' so to speak.
Its a rather long question, however it revolves around the heat equation and thus newtons law of cooling. I'll try and explain. If you can't help, nevermind.
Cylinder, 150mm high, with diameter = 50mm. Ambient temperature = 30 degrees celcius. h = 10 and k = 80 (heat transfer coefficient and thermal conductivity). Cylinder is atop a stove set to 220 degrees C. Determine the temperature of the top of the cylinder at steady state? We are told we must asnwer using finite difference method.
I know this is a big task, but if you could offer any help that would be great.
