Re: Mechanical Engineering Syllabus Gauhati University
As you are asking I am providing Gauhati University- Bachelor of Engineering (BE) - CHE517 - Mechanical Operations paper syllabus: 1. PARTICULATE SOLIDS 6 hrs. Particle characterization – particle size distribution and mean particle size. Particulate solid in bulk-agglomeration, angle of repose and friction, flow of solids in hoppers, flow of solids through orifices, conveying of solids, measurement of solid flow rate. Classification of solid particles – gravity settling, centrifugal separators, sieves, magnetic separators, electrostatic separators, floatation. 2. SIZE REDUCTION OF SOLIDS 5 hrs. Mechanism of size reduction. Energy for size reduction – energy utilization. Methods of operating crushers. Nature of materials to be crushed. Types of crushing equipments-Coarse crushers, Intermediate crushers, Fine crushers, Vibration mills, Colloid mills, Fluid energy mills. 3. MOTION OF PARTICLES IN A FLUID 5 HRS. The drag force on a spherical particle – total force on the particle – effect of motion of the fluid – terminal falling velocities. Non-spherical particles – effect of shape& orientation on drag – terminal falling velocities. Motions of bubble and drops. Acceleration motion of a particle in the gravitational field. Motion of particles in a centrifugal field. 4. SEDIMENTATION 4 HRS. Gravitational sedimentation – Fine suspensions – Coarse suspensions – Solids flux in batch sedimentation – The Kynch theory of sedimentation – thickner. Centrifugal separation – behaviour of liquids in centrifuge basket – fluid pressure – sedimentation in a centrifugal field – separation of two immiscible liquids – centrifugal equipment. 5. FLUIDISATION 5 hrs. Characteristics of fluidized systems – properties of gas – solids and liquid – solids systems – effect of fluid velocity on pressure gradient – minimum fluidizing velocity. Liquid-solid system-bed expansion-liquid and solid mixing. Gas-solid systems-bed characteristics-properties of bubbles in the bed-gas and solid mixing. Mass and heat transfer between fluid and particles. Application of the fluidized solids techniques-fluidized bed catalytic cracking-application in chemical industries-fluidised bed combustion. 6. PNEUMATIC AND HYDRAULIC CONVEYING 2 hrs. Pneumatic conveying-vertical and horizontal. Hydraulic conveying-homogenous flow-horizontal transport of settling suspensions-vertical transport-industrial applications. 7. GAS CLEANING. 3 hrs. Gravity separators, centrifugal separators, inertia or momentum separators, fabric filters, electrostatic precipitators, liquid washing, Agglomeration and coalescence. 8. FILTRATION 7 hrs. The theory of filtration – relation between thickness of cake and volume of filtrate-flow of liquid through the cloth-flow of filtrate through the cloth and cake combined, compressible filter cakes. Filtration practice-The filter medium-blocking filtration, effect of particle sedimentation on filtration-delayed cake filtration-preliminary treatment of slurries before filtration-washing of filter cake. Filtration equipment Filtration in a centrifuge Filtration calculations. 9. MIXING AND AGITATION. 3 hrs. Agitation of liquids – Purpose of agitation-agitation equipment-Impellers-Flow patterns in agitation vessels-circulation rate- velocity gradients in agitated vessels-power correlations for specific impellers-effect of system geometry-calculation of power consumption. |
