Dynamic Balance: The Steady State. Physiologic mechanisms must be understood in the context of the body as a whole. The person, as a living system, has both an in-ternal and an external environment, between which information and matter are continuously exchanged. Within the internal environment each organ, tissue, and cell is also a system or sub-system of the whole, each with its own internal and external en-vironment, each exchanging information and matter Fig. 6-1 .

A steady-state economy - The Ecologist

The notion of a steady state has meant different things at different times in history. To the traditional or classical economist, the steady state takes the biophysical dimensions of the planet — including population and available resources — as given and adapts technology and tastes to these objective conditions.

Some ecosystems exist in a steady state, or homeostasis. In steady-state systems, the amount of input and the amount of output are equal. In other words, any matter entering the system is equivalent to the matter exiting the system.

Mass and Energy Balances

Mass balance problems can be divided into those that are in steady state and those that are non-steady state. A steady-state situation is one in which things do not change with time---the incoming concentration and flow rate are constant, the outgoing flow rate is constant, and therefore the concentration in the control volume is constant. For steady-state systems, then,

Dynamic Modelling of Temperature in a Wet Ball Mill Based on ...

But these models do not consider the energy balance inside the mill and are mainly based on steady state analysis. Apart from mass and size balance, energy balance is a key aspect in control and optimization of a comminution process. Energy balance data is related to mill temperature where the latter is believed to be a primary indi or of in-mill process dynamics 21, 12 .

Steady-state operation: Under steady-state, the values of all variables associated with the process do not change with time. That is, at any given lo ion in the process, the values of temperature, pressure, composition, flow rates, etc. are independent of time. Even though a process may be steady state, it is important to realize that ...

Reactor Criticality - Nuclear Power

This state is the same state as the critical state from basic classifi ion. The prompt subcritical and delayed subcritical state is defined as: k eff 1; ρ 0, where the reactivity of a reactor is lower than zero. In this case, the production of all neutrons is insufficient to balance neutron losses and the chain reaction is not self-sustaining.

What Is the Difference Between Static and Dynamic Loads?

Static Load vs. Dynamic Load The main difference between a static and dynamic load lies in the forces produced by the weight of an object. When static, the load remains constant and doesn& 39;t change over time. With a dynamic load, some outside factor causes the forces of the weight of the load to change. Some of the factors that can affect a load ...
