Most substances are mixtures of two or more components. Separation techniques are used to remove unwanted materials
Textbook covers engineering principles, units, and conservation laws. Discusses momentum transfer, fluid statics, and overall balances. Covers steady-state and unsteady-state heat transfer mechanisms. Explores molecular diffusion in gases, liquids, and solids
Separation techniques isolate components from mixtures based on physical properties. Mixtures contain elements and compounds not chemically combined. Techniques help determine properties and produce useful substances
Handpicking separates impurities by hand when mixture contains different colors. Threshing loosens edible parts from non-edible parts in agriculture. Winnowing separates grains from straw using air current
Handpicking separates large, visible particles. Sieving separates particles based on size using porous sieves. Filtration removes insoluble solids from liquids using filters. Magnetic separation uses magnets to separate magnetic materials
