CHBE 241 Material and Energy Balances Department of Chemical and Biological Engineering The University of British Columbia Assignment #2 Due: Monday, 6 October 2008, 4:30pm CHBE Main Office 1. Assume air is an ideal gas. What is the density of air at 0 C and 1 atm, in units of kg/m 3 ? What is the approximate mass (in tonnes) of a cubic mile of air? The density of water is approximately 1000 kg/m 3 , and that of gold is 19,310 kg/m 3 . If a typical textbook were made out of air, water, or gold, about what would it weigh in pounds? 2. Air flows into a reactor at 16 kg/min. Plot the volumetric flow rate (m 3 /min) at a range of temperatures from 20 F to 300 F (step 20 F) at 20 psia pressure, and at a range of pressures from 20 psia to 200 psia (step 20 psi) at 80 F. Use the ideal gas law to model the specific volume of air as a function of pressure and temperature. 3. Curious Carl is very curious: He wants to know if CO 2 really follows the ideal gas law. To test this, he puts 1 mol CO 2 into a rigid container with a volume of 22.414 L. Then Curious carefully changes the temperature of the container and measures the pressure. After
