Chapter 3 Calculation/Short Answer Problems: 3.1 Consider a pure oxygen tank storage system for a fuel cell used in a space application. What mass of oxygen can be stored in a 2m3 tank at 34 MPa, 20◦C. Compare the results you get with the ideal gas law, the van der Waals EOS, and the generalized compressibility chart. Using the generalized compressibility chart, determine at what storage pressure the correction on the ideal gas law is 5%? Soln: Assuming temperature is constant: With I...
