Medical Hydrology and Balneology: Environmental Aspects
Using a thermometer with a Pt 100 probe, monitor the temperature of the mud at
15 second intervals until it reaches 36º C.
The time-temperature curve is created and the equation that best fits the experimental
curve is:

where, t0 is the time of inertia; small initial plateau where the temperature is kept
constant and t1 is the relaxation time that in mechanics and electricity is defined as
the time required for a magnitude that is exponentially decreasing to decrease its
initial value a 63.22% of amplitude A (45-37° C) 3 . A is the thermal amplitude,
difference between the initial temperature of the hot product, and the cold focus.

The parafangos show relaxation times higher than peloids.
Among the peloids, those from Caldas de Bohí and Archena have the higher relaxation
times.
