Whiting, Robert L. The material-energy balance developed in this study has been used successfully to match performance and to forecast production for the Wairakei geothermal field of New Zealand. The equations should be applicable to other geothermal fluid reservoirs, provided the assumptions used are realistic. The basic study from which this paper was prepared was started as the result of the growing need throughout the world for increasing quantities of energy in all forms. Quite obviously, natural forms of energy that are readily available at low development cost are those in greatest demand.
Material and energy balances are very important in the food industry. entering; or some unchanging constituent, such as in combustion calculations with air It is possible to solve such a problem formally using algebraic equations and.

A mass balance , also called a material balance , is an application of conservation of mass 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. The exact conservation law used in the analysis of the system depends on the context of the problem, but all revolve around mass conservation, i. Therefore, mass balances are used widely in engineering and environmental analyses. For example, mass balance theory is used to design chemical reactors , to analyse alternative processes to produce chemicals, as well as to model pollution dispersion and other processes of physical systems. Closely related and complementary analysis techniques include the population balance , energy balance and the somewhat more complex entropy balance. These techniques are required for thorough design and analysis of systems such as the refrigeration cycle.
Она описала дугу и, когда он отпустил руку, с грохотом закрыла люк. Шифровалка снова превратилась в затихшую черную пещеру. Скорее всего Северная Дакота попал в ловушку. Стратмор опустился на колени и повернул тяжелый винтовой замок. Теперь крышку не поднять изнутри.
А ты как думаешь. И уже мгновение спустя ее осенило. Ее глаза расширились. Стратмор кивнул: - Танкадо хотел от него избавиться.
