5. Heat Transfer
 The science that deals with the
determination of the rates of such energy
transfers due to non-equilibrium of
temperature is Heat Transfer.

6. How heat is transferred?
 There are three modes of HeatTransfer.
 Which are:
1. CONDUCTION
2. CONVECTION
3. RADIATION

7. EXAMPLES:

8. Conduction:
 It is the mode of heat transfer from high
energetic particles to low energetic
particles of the same substance.
 It can take place in solids, liquids and
gases.
 It requires direct physical contact.

9. CONDUCTION OF HEAT
ALONG COMPOSITE BAR
 The apparatus which is used to measure
the conduction of heat.

12. PROCEDURE:
 Select an intermediate position for the
heater power control.
 Allow sufficient time for a steady state
condition to be achieved before recording
the temperature ( T ) at all the four
sensor points.
 The input power reading on the
wattmeter ( Q ).

13.  This procedure should be repeated for
other input powers up to the maximum
setting of the control.
 After each change, sufficient time must be
allowed to achieve steady state
conditions.

14. DESCRIPTION
 Thermal conduction is the mode of heat
transfer, which occurs in a material by
virtue of temperature gradient. A solid is
chosen for the demonstration of pure
conduction since both liquids and gases
exhibit excessive convective heat transfer.
