Paper of Heat transfer Operations is the study of transfer of heat from one physical system to another system. Heat transfer is classified into different mechanisms such as phage transfer & heat conduction. Transfer of heat occurs by the method of conduction.

Importance of heat transfer Operations:

Heat transfer is very important as it has a broad application in various devices & systems. Good heat absorbers or a good heat emitter, both have a major role in physical world. Many industries are depending on the mechanisms of heat conduction.

Paper Pattern:

Paper of heat transfer operations contains 7 questions in it and there are 5 questions which are needed to be attempted. Each question carries equal value of marks. Question no. 1 is compulsory and remaining 4 are to be chosen from rest 6 questions. There is no chance for the students to score full marks as it is a subjective paper.

Frequently asked questions:

Paper contains questions such as derivation ofsteady state general heat conduction equation without heat generation in spherical systems, mode of conduction heat transfer, various types of fin configurations, heat transfer coefficient, Biot and Fourier numbers & their physical significances, Reynolds analogy, relation between fluid friction and heat transfer, hydrodynamic boundary layer, thermal boundary layer, Prandtl number, coefficient of heat transfer from a vertical plate, drop-wise condensation, exit fluid temperatures, absorptivity, reflectivity & transmissivity etc.

Marks and time:

Paper contains total of 100 marks in it and time allotted to this paper is 3 hours only.
