Principle of balance equations. What quantities can be balanced? Discuss the terms: system and itsboundaries, time (period) of balancing, stream, accumulation, source/sink (or generation/consumption),fictitious stream, base of balancing. Formulation of material balance equations, overall balance, componentbalances, number of independent balance equations. Auxiliary (additional) equations: conversion, yield,excess/surplus. Data matrix, usage. Recommended steps in setting up and solving balances
