In physics, a mass balance, also called a material balance, is an application of conservation of mass [1] to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique.
Direct material input (DMI) is a measure of the total material inputs into an economy and is calculated as the sum of domestic extraction (DE) and imports. The physical trade balance (PTB) is a measure of net-imports and is calculated as the difference between imports and exports. Reflecting that material and money flow in opposite directions ...
Material balancing involves taking a survey of the available inputs and raw materials in an economy and then using a balance sheet to balance the inputs with output targets specified by industry to achieve a balance between supply and demand. This balance is used to formulate a plan for resource allocation and investment in a national economy ...
Energy balance, in terms of energy economics, is concerned with all processes within an organization that have a reference to energy. It derives from the ecobalance and has the ambition to analyze and verify the emergence, transformation and use of energy resources in an organization in detail. [ 1 ]
Example of a Sankey diagram Sankey's original 1898 diagram showing energy efficiency of a steam engine. Sankey diagrams are a data visualisation technique or flow diagram that emphasizes flow/movement/change from one state to another or one time to another, [1] in which the width of the arrows is proportional to the flow rate of the depicted extensive property.
Energy balance (energy economics), verification and analysis of emergence, transformation and use of energy sources within an economic zone Energy economics , where the energy balance of a country is an aggregate presentation of all human activities related to energy, except for natural and biological processes
A contact equilibrium may be regarded also as an exchange equilibrium. There is a zero balance of rate of transfer of some quantity between the two systems in contact equilibrium. For example, for a wall permeable only to heat, the rates of diffusion of internal energy as heat between the two systems are equal and opposite.
