Entropy, Water and Resources: An Essay in Natural by Horst Niemes

By Horst Niemes

This ebook on the intersection of typical sciences, economics, and water engineering goals to minimize the gaps among monetary conception, ordinary sciences, and engineering perform. in response to a longer thermodynamic strategy, the authors clarify which fiscal assumptions are appropriate for developing a dynamic version that's in step with the normal sciences. particularly, the targeted function of water within the construction and replica actions could be regarded as an indispensable part. Water is generated in a separate water therapy method and is used to move the unavoidable by-products of construction and copy actions to a wastewater quarter. during this recognize, not just environmental safety points, but additionally the interrelation among the water necessities and using non-renewable assets for generating wanted intake items may be highlighted.

Example text

8 (for the usage of water in production and reproduction activities) The produced water will be used to transport the unavoidable by-products from the different processes of the production and the reproduction sectors to the wastewater treatment sector. The wastewater generation rates are defined as the quotient between the wastewater amounts and the water amounts. These rates are used for the different economic transformation processes and are set to equal 1. The large amounts of water that are required in the energy production process for cooling the water will not be considered.

For the energy production process, however, a third step must be added, namely the generation of useful energy from raw material. 1 Structure and Characteristics of the Water Use Model 43 the energy sector E during the production interval τ . The average concentration c(N¯ E (τ ))of material N E (τ ) should be a declining function similar to the one in Eq. 2). One unit of raw material for energy production, however, should have a time-invariant, embedded, specific energy content σ E (NeE ), which leads us to the simple linear relation between energy and raw materials shown in Eq.

Capital inputs for the extraction processes will not be considered in our basic model. Q Let the concentration of the desired raw material Ni (τ ) ∧ NμK (τ ) in the natQ ural environment be described as c (Ni (τ )) ∧ c (NμK (τ )). If this concentration is lower than the assumed target concentrations, c∗ = 1, then, in the first step of the extraction process, more material in the amount of the reciprocal value of the Q concentrations 1 c(Ni (τ )) ∧ 1 c(NμK (τ )) , must be appropriated from the natural environment for separating one unit of the desired raw material in the second step.
