The study of marine engineering refers to the whole fundamentals of science and engineering behind the building of ships, different kinds of marine vessels, oil rigs, etc. The paper of Thermo Dynamics along with the study of Heat transfer seeks to explore the detailed relation of heat to work and energy. This paper incorporates topics like the Kelvin- Planck statement and the statement of second law of thermodynamics and their equivalence, Carnot cycle and the derivation of expressions of the efficiency of Carnot cycle, the shell and tube heat exchanger, Reynolds Prandelt, Nusselt and Grashof number , determination of blade efficiency , axle thrusts, stage efficiency and numericals demanding calculations of these, calculation of indicated power, brake power and thermal efficiency, mechanical efficiency and brake thermal efficiency, concept of availability, Fourier’s law of heat conduction, calculation of work ratio and thermal efficiency, concepts of Absorptivity, Emissivity, Transmissivity and Reflectivity, Newton’s law of cooling. Below are attached some of the previous year’s questions papers for your help.
