It is observed that for Fo greater than 0.2, considering only the
first term of the series and neglecting the other terms, the numerical
value goes on decreasing, and it involves an error of less
than 2%. Generally, for the Fourier number less than 0.2, it becomes
very useful and convenient to use the one term approximation
solution. The variation of temperature was measured at the centre
of cylinder with time and these values were put in the equation of
transient heat conduction, which provided n number of equations.
The solution of these equations provided the value of specific heat
capacity and thermal conductivity of the pellets. Those values
which were far away from the cluster formed in graph were
discarded
