This Unit of Study is a shorter version of content in AMME2261 + AMME2262 and suits Biomedical (Mechanical Major) and Mechatronics students. Students will get a practical, introductory course in Fluid Mechanics, Heat Transfer and Thermodynamics. Basic principles and applications in these areas are covered. The emphasis is on learning how to tackle the variety of problems which engineers encounter in these fields. Fluid Mechanics Properties: viscosity, surface tension, cavitation, capillarity. Hydrostatics: manometers, forces and moments on submerged surfaces, centre of pressure, buoyancy, vessel stability. Flow: Streamlines, turbulence, continuity, Bernoulli, venturi meter, pitot tube, head, loss coefficients, pumps, turbines, power, efficiency. Fluid momentum, drag, thrust, propulsive efficiency, wind turbines, turbomachinery, torque, power, head, Francis, Pelton, Kaplan turbines. Dimensional analysis, similarity, scale modelling, Reynolds No. , pipe flow, pressure drop, Moody chart. Heat Transfer Conduction: thermal circuits, plane, cylindrical, conduction equation, fins. Heat Exchangers: LMTD and NTU methods. Unsteady Conduction: lumped capacity, Bi, Fo, Heissler charts. Convection (forced), analytical Nu, Pr correlations. Convection (natural) Ra, Gr. Radiation spectrum, blackbody, emissivity, absorptivity, transmissivity, Stefan-Boltzmann, Kirchhoff Laws, selective surfaces, environmental radiation. Thermodynamics: 1st Law of Thermodynamics, Properties, State postulate. Ideal gases, 2-phase properties, steam quality. Turbines, compressors. thermal efficiency and COP for refrigerators. 2nd Law of Thermodynamics, Kelvin-Planck, Clausius statements. Carnot engine. Entropy; increase of entropy principle, entropy and irreversibility. Isentropic processes, T-s diagrams, isentropic efficiency. Some power and refrigeration cycle analysis, characteristics of main power cycles. Psychrometry, air-conditioning, thermal comfort basics.
