produce to food; Classification into momentum, heat and mass transfer
operations; Necessity of estimating their transfer rates as function of driving
force Momentum Transfer: Pressure drop-flow rate relationship for flow
through pipe, rectangular conduit and extruder in laminar flow; Turbulent
flow and fanning’s friction factor; Compressible flow: flow through nozzle
and porous media; Apparent viscosity, generalized viscosity coefficient and
generalized Reynolds number for non-Newtonian fluids; Non-Newtonian
liquid flow in pipes and slits Heat Transfer: Steady state heat transfer in conduction, convection and
radiation; Overall heat transfer coefficient; Forced, natural convection,
condensation and boiling heat transfer; Tubular and plate and fin type heat
exchangers and estimation of their effectiveness; NTU-Effectiveness
relationship; Unsteady state heat transfer in plate, cylinder and spherical
bodies; Numerical methods in heat transfer.
Mass Transfer: Molecular diffusion and Fick’s Law; Steady state mass
transfer in equimolar counter diffusion and diffusion through stagnant
medium; Diffusion through varying cross sectional area; Convective mass
transfer and mass transfer coefficient; Mass transfer coefficients; Unsteady
state mass transfer in plate, cylinder and spherical bodies; Analogy between
