**ME8693 HMT HEAT AND MASS TRANSFER**

1.Define heat transfer and write the different types.

2.What are the factors affecting thermal conductivity of material?

3.A plane wall 20 cm thick generate heat at the rate of 4 x 104 W/m3 when an electric current is passed through it. The convective heat transfer co efficient between each face of the wall and ambient air is 60 W/m2K. Determine the surface temperature. Assume the air temperature to be 20°C and k for wall is 15 W/mK.
