Question

Problem 2: (10 points) Docs vapor water at T 438.8 "Cand P 22089 kPa behave like an ideal gas? (a) (5 points) Write the condition that needs to be satisfied for an ideal gas behavior. (b) (5 points) Mark with a large dot the point (Pr.T) for this specific case and estimate the value of Z. Hint: Temperatures used for estimating Trneed to be expressed in Kelvin. 1.3 SIMPLE FLUID 1.2 Ze 02901 0.9 0.8 0.7 0.6 E 0.5 0.4 0.3 0.2 0.1 saturated liquid 10 0,1 0.0 Reduced pressure, Pr FIGURE D.1 Lee-Kesler simple fluid compressibility factor.

Explanation / Answer

a. For a gas to be considered ideal the compresibility factor Z, value should be equal to 1, such that the equation PV = ZnRT becomes the ideal gas equation PV = nRT.

b. in the diagram, all conditions that makes a value of Z, compresibility factor, equal to 1 is ideal. Therefore, from Pr = 0.01 to Pr = 0.1, it can be considered ideal. Any variation can be considered otherwise.
