Clearing internal heat

First, herbs that are bitter and cold or pungent and cold, can directly clear internal heat, and particularly enter the meridians and organs where the heat stays, are selected. 

Within this formula, mix-fried Licorice, sweet and warm, boosts the qi so as to fortify the spleen. It also harmonizes the other medicinals in this formula. Bupleurum penetrates the exterior and upbears yang so as to soothe depression. At the same time, because it is acrid and cool, it clears internal heat by out-thrusting it. 

Figure 20.4 shows the interaction between one zone and the others as well as the internal heat and mass flows between the layers. Clearly a number of assumptions are made in writing any model such as this. For example, here it is assumed that the interface between the brine and chlorine is insulating so that there is no heat transfer between the two phases. 

Beginning of internal heat add Shi Gao [Gypsum) to clear the heat. 

Vertically propagating Kelvin and mixed Rossby-gravity modes have been identified in the stratosphere the evidence in the troposphere is less clear. Internal oceanic Kelvin waves are considered by many oceanographers to be the piimaiy mechanism for the eastward transport of heat along the equator associated with the significant in-terarmual phenomenon known as the El Nino/Southem oscillation (ENSO), which affects weather and chmate globally. 

We can clearly understand the physical implication of (3.46) The change of internal heat energy dUq consists of two parts i.e., the change of irreversible internal mechanical energy dU and the heat supply dQ due to an energy flux. 

Commonly used heat-transfer surfaces are internal coils and external jackets. Coils are particularly suitable for low viscosity Hquids in combination with turbine impellers, but are unsuitable with process Hquids that foul. Jackets are more effective when using close-clearance impellers for high viscosity fluids. For jacketed vessels, wall baffles should be used with turbines if the fluid viscosity is less than 5 Pa-s (50 P). For vessels equipped with cods, wall baffles should be used if the clear space between turns is at least twice the outside diameter of the cod tubing and the fluid viscosity is less than 1 Pa-s (10... 

Saline Water for Municipal Distribution. Only a very small amount of potable water is actually taken by people or animals internally, and it is quite uneconomical to desalinate all municipally piped water, although all distributed water must be clear and free of harmful bacteria. Most of the water piped to cities and industry is used for Htfle more than to carry off small amounts of waste materials or waste heat. In many locations, seawater can be used for most of this service. If chlorination is requited, it can be accompHshed by direct electrolysis of the dissolved salt (21). Arrayed against the obvious advantage of economy, there are several disadvantages use of seawater requites different detergents sewage treatment plants must be modified the usual metal pipes, pumps, condensers, coolers, meters, and other equipment corrode more readily chlorination could cause environmental poUution and dual water systems must be built and maintained. 

Clearly, Aid is equal to the heat transferred in a constant pressure process. Often, because biochemical reactions normally occur in liquids or solids rather than in gases, volume changes are small and enthalpy and internal energy are often essentially equal.
