Mass and Energy Balances - MTU

Mass and Energy Balances One of the fundamental laws of physics states that mass can neither be produced nor destroyed---that is, mass is conserved. Equally fundamental is the law of conservation of energy. Although energy can change in form, it can not be created or destroyed. These two laws of physics provide the basis for two tools which are ...
