Heat factor

Sensible Heat Factor. The ratio of the change in sensible (constant moisture content) cooling enthalpy to the change in total cooling enthalpy. 

For estimates of both Ed and fcd in the Arrhenius equation, in principle two different points on a desorption peak or two runs with different heating factors o2 are required. One obvious point is the maximum of the peak, and very often only this is used while the value of kd is supposed to be of the order of magnitude 1012 to 1013 sec-1. As seen from Eq. (28), the location of Tm depends but weakly on fcd as compared to its dependence on Ed, so that an uncertainty in the value of kd of one order of magnitude does not affect the estimated value of Ed appreciably. This has been clearly illustrated by analogue simulation of the thermodesorption processes (104). On the other hand, the said fact causes the estimates of kd to be very uncertain. A recently published computational analysis of the peak location behavior shows the accuracy of the obtained values of Ed (105). 

There are two heat factors involved in cUiy phase change. They are "heat capacity", i.e.- Cp or Cy, and "heat of transformation", usually denoted as H. 

The absence of the heating factor and the wash-out factor should be emphasized in addition, industrial emissions can be split into two sources. 

Parvovirus B19 transmission occurred in a child who had received vapor heat-treated prothrombin complex concentrate (60° C for 10 hours and 80° C for 1 hour) and in another child who received dry-heated factor VIII concentrate (80° C for 72 hours). Both children had severe hemophiha A and were treated for factor VIII inhibitors (52).

We assume that the medium density and viscosity are independent of concentration and temperature, and hence, the concentration and temperature distributions do not affect the flow field. This allows one to analyze the hydrodynamic problem about the fluid motion and the diffusion-heat problem of finding the concentration and temperature fields independently. (More complicated problems in which the flow field substantially depends on diffusion-heat factors will be considered later in Chapter 5.) It is assumed that the information about the fluid velocity field necessary for the solution of the diffusion-heat problem is known. We also assume that the diffusion and thermal conductivity coefficients are independent of concentration and temperature. For simplicity, we restrict our consideration to the case of two-component solutions. 

SENSIBLE HEAT FACTOR - The ratio of sensible heat to total heat. 

The radiative heat factor has been calculated using a cubic array packing with a void fraction e = (0.5 — 0.35). The effective thermal conductivity involving the void fraction, which is frequently used in estimating the bed heat transfer, is expressed as (Schotte, 1960)...
