Mass and Energy Balances In this chapter we will apply the conservation of mass and conservation of energy laws to open systems or control volumes of interest The balances will be applied to steady and unsteady system such as tanks, turbines, pumps, and compressors 4 1 Conservation of Mass The general balance equation can be written as
• Energy balance – For any system, the energy going into the system must equal the energy coming out of the system plus any accumulation of energy in the system • Only ONE energy balance equation is written for any system (or sub-system) irrespective of the number of components in the product(s) Note: Once mass and energy balance

process flow, Material and energy balance diagrams Material quantities, as they pass through processing operations, can be described by material balances
In this chapter we will apply the conservation of mass and conservation of energy If there is no chemical reaction, the mass balance equation is simplified to cv
