4. MATERIALAND ENERGY BALANCE
beeindia.gov.inEnergy balances are often complicated because forms of energy can be interconverted, for example mechanical energy to heat energy, but overall the quantities must balance. 4.2 The Sankey Diagram and its Use The Sankey diagram is very useful tool to represent an entire input and output energy flow in any energy equipment or
Chapter 8 and 9 – Energy Balances
faculty.poly.eduChapter 8 and 9 – Energy Balances Reference States. Recall that enthalpy and internal energy are always defined relative to a reference state (Chapter 7). When solving energy balance problems, it is therefore necessary to define a reference state for each chemical species in the energy balance (the reference state may be predefined if a ...
