Department of Chemical Engineering ChE 110A University of California, Santa Barbara Winter 2010 Problem Set No. 9 Due: Friday, March 12, 2010 Objective : To understand and perform calculations for open and cyclical processes with applications to power plants and process equipment. Note: Numerical values for some problems have been changed from those in the book. Problem 45 ( survey question) If you could trade time spent on one topic for another this quarter, which topic would you reduce and which would you increase? Problem 46 ( Smith, van Ness, Abbott, 6.14m, page 242) Calculate g1852 , g1834 g3019 , and g1845 g3019 by a suitable generalized correlation for propane at 375 K and 25 bar. Problem 47 ( Smith, van Ness, Abbot, 6.33, page 244) A rigid vessel of 0.25 g1865 g2871 capacity is filled with saturated steam at 1500 g1863g1842g1853 . If the vessel is cooled until 25% of the steam has condensed, how much heat is transferred and what is the final pressure? Problem 48 ( Smith, van Ness, Abbott, 7.25a, page 283) An adiabatic gas turbine has an inlet stream at 500 g1837 and 6 g1854g1853g1870

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
