Heat capacity of tungsten and copper PLEASE!
Organization:
http://groups.google.com/
Hi there, can anyone please post me
the heat capacity of tungsten at
about 3000 k and copper, because I'm
doing calculations on cathodes
spots, and I'm using average heat
capacities of these two cathode
materials, betwen 3000 k and 4000k. This
may sound stupid but I can't
find them anywhere. By this time I have to
calculate the time
necessary for the cathode Temp, rise from one To to T,
and I'm having
results that are 100 times less that they should. By the
way in these
calculations I'm using Cp (W)= 130 J kg-1 K-1, I know that
this value
is wrong but is the only one I have. Plase can anyone post me
an
average Heat capacity of Tungsten and copper at [ 3000 - 3653 ]
k.
Thank you!
