ME- 316 E HEAT TRANSFER LAB.

Sessional : 50 Marks
Practical : 50 Marks

List of Experiments :

1. To determine the thermal conductivity of a metallic rod.

2. To determine the thermal conductivity of an insulating power.

3. To determine the thermal conductivity of a solid by the guarded hot plate method.

4. To find the effectiveness of a pin fin in a rectangular duct natural convective condition and plot temperature distribution along its length.

5. To find the effectiveness of a pin fin in a rectangular duct under forced convective and plot temperature distribution along its length.

6. To determine the surface heat transfer coefficient for a heated vertical tube under natural convection and plot the variation of local heat transfer coefficient along the length of the tube. Also compare the results with those of the correlation.

7. To determine average heat transfer coefficient for a externally heated horizontal pipe under forced convection & plot Reynolds and Nusselt numbers along the length of pipe. Also compare the results with those of the correlations.

8. To measure the emmisivity of the gray body (plate) at different temperature and plot the variation of emmisivity with surface temperature.

9. To find overall heat transfer coefficient and effectiveness of a heat exchange under parallel and counter flow conditions. Also plot the temperature distribution in both the cases along the length of heat of heat exchanger.

10. To verify the Stefen-Boltzmann constant for thermal radiation.

11. To demonstrate the super thermal conducting heat pipe and compare its working with that of the best conductor i.e. copper pipe. Also plot temperature variation along the length with time or three pipes.

12. To study the two phases heat transfer unit.

13. To determine the water side overall heat transfer coefficient on a cross-flow heat exchanger.

14. Design of Heat exchanger using CAD and verification using thermal analysis package eg. I-Deas etc.

Note:

1. At least ten experiments are to be performed in the semester.

1. At least seven experiments should be performed from the above list. Remaining three experiments may either be performed from the above list or designed & set by the concerned institute as per the scope of the syllabus.
