The lumped heat capacity analysis method was used
to determine h (Holman, 1996). The method involves
measuring temperature changes of objects of known
shape and with high thermal conductivity (such as aluminum
or copper) and the use of appropriate equations
to estimate h for the process. If Biot number is less than
0.1, h can be calculated from the relation below for
lumped heat transfer (Incropera & Dewitt, 1996).
