Objectives The student is expected to acquire a basic understanding of the following: conservation and general balance equations with regard to accumulation, convective and non-convective transfer and generation; use of the general balance equation for total mass, species mass, total energy and linear momentum; chemical reaction leading to generation; non-convective transfer of energy leading to heat transfer; non-convective transfer of momentum leading to shear stress via Newton's law of viscosity; formulation of dimensionless groups.
Synopsis Application of mass, total energy and linear momentum conservation to the following processes: steady continuous processes with and without reaction; unsteady flow from a tank and behaviour of continuous mixing vessels; batch and steady flow energy transfer with specific reference to power generation; rate of heat transfer by conduction and by convection in plane and cylindrical geometries using Fourier's law and heat transfer coefficients; concentric pipe heat exchangers in co-current and counter current flow; log mean temperature difference; steady pipe flow and the significance of the Reynolds number.
