Q.1 Discuss in detail the aims of studying heat transfer and its various applications.

Q.2 a) What is convection heat transfer? Why is it considered to be a mode of heat transfer?

b) Give two examples each of natural and forced circulation

Q.3 A hot plate of area 0.5 m2 is maintained at a temperature of 600 C by a 100W electric heater when room temperature is 300 C. The appropriate convection coefficient is 2.15 (T)1/3 W/m2K.
