Chemical Engineering
(1) Transport phenomena: (Under steady state conditions):
(a) Momentum transfer
(i) Different patterns of flow and their criteria. (ii) Velocity profile.
(iii) Filtration: sedimentation; centrifuge. (iv) Flow of solids through fluids.
(b) Heat transfer:
Different modes of heat transfer; Conduction-calculation for single and composite
walls of flat, cylindrical and spherical shapes.
Convection-different dimensionless groups used in force and free convection.
Equivalent diameter. Determination of individual and overall heat transfer
coeff.
Evaporation-Radiation-Stefan Boltzmann-law.
Emissivity and absorptivity. Geometrical shape factor. Heat load of furnaces-calculation.
(c) Mass transfer:
Diffusion in gases and liquids. Absorption, desorption, humidification, dehumidification,
drying and distillation. Analogy between momentum, heat and mass and transfer.
(2) Thermodynamics:
(a) lst, 2nd and 3rd laws of thermodynamics.
(b) Determination of internal energy, entropy, enthalpy and free energy-Determination
of chemical equilibrium constants for homogeneous and heterogeneous systems.
Use of thermodynamics in combustion, distillation and heat transfer. Mechanism
and theory of mixing various mixers for liquid-liquid, solid-liquid and solid-solid.
(3) Reaction Engineering:
(i) Kinetics: Homogeneous and heterogeneous reactions. 1st and 2nd order reactions.
Batch and flows-Reactors and their design.
(ii) Catalysis-Choice of catalyses.
Preparation: Mechanics of catalysis based upon mechanism.
(4) Transportation:
Storage and transport of materials and in particular powders, resins, volatile
and non-volatile liquids, emulsions and dispersions, pumps, compressors and
blowers. Mixers-Mechanisms and theory of mixing various mixers for liquid-liquid,
solid-liquid, solid-solid.
(5) Material:
Factors that determine choice of materials of construction in chemical industries-Metals
and alloys, ceramics, plastics and rubbers. Timber and timber products, plywood
laminates.
Fabrication of equipment with particular reference to production of vats,
barrels, and filter presses, etc.
(6) Instrumentation and process control:
Mechanical, hydraulic, pneumatic, thermal, optical, magnetic, electrical and
electronic instruments. Controls and control systems. Automation.
