The tremendous advantages of the integral heat method over the directly measured heat capacities are that heat measurements can be made down to 10" to 10" in contrast to 0. Im, and that the theoretical [Pg.40]

Use the integral equation method to derive an expression for the variation of the local heat transfer rate along a wide flat plate buried in a porous medium through which [Pg.548]

Fortunately another method exists that does appear promising. Cobble and co-workers " have used an integral heat method of evaluating for aqueous solutions over a rather wide temperature range. For the dissolution of one mole of an electrolyte to form an infinitely dilute solution [Pg.39]

Eq. 6 allows us to calculate the total integral heat of adsorption on an energetically homogeneous surface using density functional theory or other simulation method. To calculate the heat of adsorption on a real surface we must first determine the distribution of adsorptive [Pg.85]

Consider a flat plate whose heated section is maintained at a constant temperature (T = constant for.r > ). Using integral solution methods (see Kays and Crawford, 1994), the local Nusselt numbers for both laminar and turbulent flows are determined to be [Pg.422]

As typical representatives for slow heat release appliances a soapstone stove and a tiled stove were used for the tests. The third type of slow heat release appliance was equipped with an integrated heat exchanger to supply hot water for a central heating system. This appliance was chosen to check the feasibility of the new test method in view of the necessary recording of the heat split between heat released to the room and heat released to the central heating system.

Della Gatta et al. (15) obtained diflerential heats of water adsorption on jj-AljOj by diflerentiation of a polynomial function expressing the entire integral heat curve. For this method, least squares is used to fit a polynomial of the form [Pg.167]

The mathematical model for the borehole grouting in the regions of permafrost is proposed and solved analytically by the approximate integral-heat-balance method. [Pg.778]

Experimentally observed quantities pertaining to the whole surface, such as the amount of adsorbed substance, heat of adsorption, reaction rate, are sums of contributions of surface sites or, since the number of sites is extremely great, the respective integrals. As increases monotonously with s, each of them can be taken as variable for integration both methods of calculation are used. If is chosen as an independent variable, a differential function of distribution of surface sites with respect to desorption exponents,
