Chapter 7 – Energy and Energy Balances
faculty.poly.eduChapter 7 – Energy and Energy Balances The concept of energy conservation as expressed by an energy balance equation is central to chemical engineering calculations. Similar to mass balances studied previously, a balance on energy is crucial to solving many problems. _____ System
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 2 MATERIAL AND ENERGY BALANCES - NZIFST
www.nzifst.org.nzCHAPTER 2 MATERIAL AND ENERGY BALANCES Material quantities, as they pass through food processing operations, can be described by material balances. Such balances are statements on the conservation of mass. Similarly, energy quantities can be described by energy balances, which are statements on the conservation of energy.
