    water is one of the components‚ and the liquid natural product being isolated (which is immiscible with water) is the other component. The product can be steam distilled from the natural source at a relatively low temperature (always less than 100 oC)‚ thus avoiding decomposition of the product.2 Steam distillation can be carried out in two ways: the direct method and the live steam method.3 In the direct method‚ steam is generated by boiling a mixture of the source of the compound of interest

    1 Chapter 1 Definition and Basic Concepts Thermodynamics is defined as the science of energy. Originally derived from Greek words : therme (heat) and dynamics (power) – descriptive of early attempts at conversion of heat into power. Modern interpretation includes all aspects of energy and energy transformations‚ power generation‚ refrigeration‚ and the relationships among properties of matter. There are two approaches in thermodynamics studies: (1) classical thermodynamics – a macroscopic

    1. Objective The aim of this laboratory experiment is to analyse the rate of heat transfer losses through convection and radiation separately from a cylindrical glass rod suspended in a pressure vessel. The variation of the dimensionless quantities; Nusselt number‚ Prandtl number and Grashof Number‚ with Pressure are to be analysed graphically as well. The experimental graph of log10(Nu) vs log10(Gr.Pr) should be plotted and analysed against the graph of the empirical equations. 2. Introduction:
