FLUID MECHANICS AND HEAT TRANSFER
1. FLUID MECHANICS
Properties of fluid such as density, viscosity and specific weight. Fluid statics, Pressure at a point, pressure variations in horizontal and vertical directions, concept of gauge and absolute pressure, use of manometer for pressure measurements. Force on plates - horizontal and inclined. Energy balance in fluid flow, types of flow, continuity equation, application to one dimensional problem, derivations of Bernoulli’s energy equation and Euler 's equation, examples illustrating the use of energy equation.
2. FLOW THROUGH PLATES AND PIPES
Classification of flow, Reynolds number, laminar flow between parallel plates and circular pipes - simple problems. Pressure in fluid flow, head loss due to friction, Dasey - Weisbach equation, flow through pipes, use of Moody's diagram - minor losses- simple problems.
3. HEAT CONDUCTION
Steady state conduction: Fourier’s equation, one-dimensional steady state heat conduction in simple and composite geometries, simple problems. Transient heat conduction: Systems with negligible internal resistance, lumped heat analysis -System with negligible surface resistance, heat flow in an infinitely thin plate (semi infinite body), Systems with finite surface and internal resistance, Chart solutions of transient heat conduction, simple problems.
4. CONVECTIVE HEAT TRANSFER
Convective heat transfer coefficient- Boundary layer concept, velocity and thermal boundary layers (no derivation), simple problems. Boundary layer development in circular ducts (no derivation), simple problems. Flow over a flat plate-laminar and turbulent boundary layers (no derivation), simple problems. Flow over cylinders and spheres, simple problems.
5. RADIATION HEAT TRANSFER
Basic laws of radiation, radiation heat transfer between surfaces, Shape factor, simple problems. Basics of mass transfer, Fick's laws of diffusion. Principles of Physical Modelling.
