Question Paper

State and explain the thermal conductivity of solids, liquids and gases.

Briefly explain the electrical analogy of heat conduction.

What is "Stefan-Boltzmann" law of radiation? Explain.

The quantity of radiation received by the Earth from the Sun is 1·4 kW/m^2 (solar constant). Assuming that the Sun is an ideal radiator, calculate the surface temPerature of the Sun. The ratio of radius of the Earth's orbit to the radius of the Sun is 216.

What is thermal insulation? Explain.

For a small diameter tube, derive the critical radius of insulation (ro)cr =2k/ha with usual notations.

State Newton's law of cooling.

Define the heat transfer coefficient. On what factors does it depend?

Explain the Lumped capacitance method for transient conduction.

What is a fin Why is it necessary to attach fins in a heat exchanger?

State and explain Buckingham 1t theorem.

What are the merits and demerits of Buckingham 1t theorem?

What is Reynolds-Colburn analogy Explain.

Explain Kirchhoff's Law. What do you mean by the statement perfect absorber of radiant energy is also a perfect emitter"?

What is Henry's Constant How do you find the Henry's Constant for gases?

What is fluidized bed combustion in boilers? Explain.

What is zero order chemical reaction and first order chemical reaction

Give the classification of heat exchangers.

10.(a) Write a note on temperature distribution in heat exchangers.

State and explain Gibbs phase rule. 4
