NOTE: All questions are compulsory

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. What fraction of the heat supplied is lost by natural convection? What happens to the rest of the heat supplied?

Q.4 The quantity of radiation received by earth from the sun is 1.4 kW/m2 (solar
