12–3C Consider the function z(x,y), its partial derivatives (z/x)yand (z/y)x, and the total derivative dz/dx. (a) How do the ...
Chapter 12 | 677 General Relations for du, dh, ds, cv, and cp 12–32C Can the variation of specific heat cpwith pressure at a giv ...
12–63 Propane is compressed isothermally by a piston– cylinder device from 100°C and 1 MPa to 4 MPa. Using the generalized chart ...
Chapter 12 | 679 12–80 Reconsider Prob. 12–79. Using EES (or other) software, solve the problem assuming steam is the working fl ...
(a) proportional to the enthalpy of vaporization hfgat that temperature. (b) proportional to the temperature T. (c) proportional ...
Chapter 13 GAS MIXTURES | 681 U p to this point, we have limited our consideration to thermodynamic systems that involve a singl ...
13–1 COMPOSITION OF A GAS MIXTURE: MASS AND MOLE FRACTIONS To determine the properties of a mixture, we need to know the compo ...
Chapter 13 | 683 EXAMPLE 13–1 Mass and Mole Fractions of a Gas Mixture Consider a gas mixture that consists of 3 kg of O 2 , 5 k ...
13–2 P-v-T BEHAVIOR OF GAS MIXTURES: IDEAL AND REAL GASES An ideal gas is defined as a gas whose molecules are spaced far apar ...
Dalton’s and Amagat’s laws can be expressed as follows: Dalton’s law: (13–6) Amagat’s law: (13–7) In these relations,Piis called ...
from ideal-gas behavior. One way of doing that is to use more exact equa- tions of state (van der Waals, Beattie–Bridgeman, Bene ...
In the van der Waals equation, for example, the two constants for the mixture are determined from (13–12a, b) where expressions ...
688 | Thermodynamics (c) When Amagat’s law is used in conjunction with compressibility factors, Zm is determined from Eq. 13–10. ...
13–3 PROPERTIES OF GAS MIXTURES: IDEAL AND REAL GASES Consider a gas mixture that consists of 2 kg of N 2 and 3 kg of CO 2. Th ...
(13–19) (13–20) (13–21) Similarly, the specific heats of a gas mixture can be expressed as (13–22) (13–23) Notice that propertie ...
where Pi,2yi,2Pm,2and Pi,1yi,1Pm,1. Notice that the partial pressure Piof each component is used in the evaluation of the entr ...
692 | Thermodynamics and Thus, Discussion We could also determine the mixture pressure by using PmVm mmRmTm, where Rm is the ap ...
Real-Gas Mixtures When the components of a gas mixture do not behave as ideal gases, the analysis becomes more complex because t ...
