   Paul,
   What is SENSIBLE energy and what is NON-USABLE sensible energy?
   George (down under)

   Sensible energy is heat or motion that can be sensed.
   Non sensible energy is chemical or gas products I think.

   Paul Lamar ...No rotor no motor.
   --------------------------------------------------------------------------------

   Here is a simple definition.

   SENSIBLE HEAT
    If a substance is heated (heat added) and the temperature rises as
   the heat is added,  the increase in heat is called sensible heat.
   Likewise, heat may be removed from a substance (heat subtracted).
   If the temperature falls, the heat removed is, again, sensible heat.

   Heat which caused a change in temperature in a substance is called
   sensible heat.

   LATENT HEAT
   A physical phenomenon of all pure substances is their ability to
   change state.  Solids become liquid, liquids become gas or the
   reverse.  These state changes occur at given temperature and
   pressure for the substance and the temperature does not change until
   the state change is complete.  Heat energy must be added or removed
   to produce the state change.
   Heat which bring about a CHANGE OF STATE, WITH NO CHANGE IN
   TEMPERATURE, IS CALLED LATENT (hidden) HEAT.
