Webmeasure of product consistency and quality. Another reason for making flow behavior studies is that a direct assessment of processability can be obtained. For example, a high viscosity liquid requires more power to pump than a low viscosity one. Knowing rheological behavior, therefore, is useful when designing pumping and piping systems. WebLet us estimate the viscosity of a gas mixture consisting of 20% Zn vapor, 50% N2, and 30% CO at 1000 oC. The density of zinc at its melting point (Tm=692 K) is approximately 7.14 g cm-3. Therefore, its molar volume at that temperature is calculated to be = 65.38/7.14 = 9.16 cm3/mole and the corresponding σ c=2.55 Å (see (3.2.3)). fly advanced hondajet
