Hi,
Can anyone give me any information on where i could find information on the emissivity of a gas, particulally argon, or how i can calculate it? i am trying to create a graph of heat transfer against temperature and see which plays a larger role at particular temperatures when transfering...
Hi,
This may seem basic bit but it is causing me a little confusion, any help would be appreseated.
In theories such as Debye / Einstein it is stated that it this is true for low temperatures, coudl someone tell me what sort of temerautres they acutally mean by this? do they mean low as in...
is there another way of considering the specific heat capaciaty of a material (many gas) other than with respect to the number of degrees of freedom with gives a constant out put for all monocrmatic gases for all temperature and pressure.
For a monocromatic gas c=(3/2)*n*R*m
where m = mass...
i could not get the equation editor to work properly (probaly the user to be fair) but i am included a hand written version as an attachment. i have managed to modifie it a bit which is giving me more sensible answers. But to get a value for time (in seconds#) i am using the below equation to...
i have set up an equation to get the heat transfer rate Q for a combined system where heat is transferred from a cylindrical outer wall set at 500 C. the wall heats a gas, which in turn heats a solid block of cylindrical metal positioned in the centre of the heated walls with a starting...
Hi could anyone advise me to weather I am right in thinking when using equation one to calculate the thermal conductivity that Cv is the molar heat capacity and is calculated by use of equation two for an ideal gas such as argon?
k=n*<v>*mfp*cv / 3*NA
Cv,m = (3/2) * R
Any hints would be...
