Measurement Systems - Philadelphia University

The output and input signals may involve energy of the same form or there may be an energy conversion from one form to another. – An active transducer has an auxiliary source of power which supplies a major part of the output power while the input signal supplies only an insignificant portion. Again, there may or may not be a conversion of energy

specify an input to a reactor of one ton of naphtha and an output of two tons of gasoline or gases or anything else. One ton of total material input will only give one ton of total output, i.e. total mass of input = total mass of output. A material balance is an accounting for material. Thus, material balances are often compared

The Cobb–Douglas Production Function

Here Y represents aggregate output, K the capital input, and N the labor input (capital and labor being the two "factors of production" in this function). The Aterm represents Total Factor Produc-tivity (TFP for short); you can think of this as a "quality" factor—as opposed to K and N which are just quantitative.

Sankey diagrams for energy balance - Statistics Explained

Use for energy balances. Sankey diagrams are ideal for visually representing energy balances. This is because an energy balance represents the contribution and flow of various energy commodities (fuels, heat and electricity, i.e. energy carriers in a marketable form) into the different sectors of the economy (e.g. supply, transformation and consumption) in energy units.
