Experiments are being conducted with regard to heat exchange systems. However,
there are errors and uncertainties attached to each system. Journals, which publish
articles concerning heat transfer experiments, require an estimate of this uncertainty.
These uncertainties must be calculated in order to determine how valid a set of results
is. The uncertainty describes to what level one may rely on a set of experimental
results and conclusions.
The uncertainty was calculated by the formulation of an uncertainty equation with the
use of various statistical methods. Adjustments or modifications had to be made to
the present uncertainty equations in order to calculate the uncertainty in heat transfer
systems.
Uncertainty based on a general uncertainty equation by Schultz and Cole (1979)
enabled the derivation of the equations to calculate the necessary uncertainty factor
for heat transfer systems. Implementation of the equations in various experimental
set-ups was achieved.
The uncertainty equations yielded results that seemed consistent with the subjective
view of the experimenter.
Therefore, the equations were considered valid.
