Unformatted text preview: Department of Chemical Engineering ChE 110A University of California, Santa Barbara Winter 2010 Problem Set No. 8 Due: Wednesday, March 3, 2010 Objective : To understand and perform calculations involving fundamental thermodynamic relations and potentials ( g,G,¡,¢, and £ ), and applying ¤¥¦ models, § ¨ models, and data from steam tables for open and closed processes. Note: Numerical values for some problems have been changed from those in the book. Problem 38 ( thought problem) Are adiabatic processes always reversible? Are reversible processes always adiabatic? Are reversible processes always isentropic? Are reversible, adiabatic processes always isentropic? Problem 39 ( Smith, van Ness, Abbott, 5.28a, page 195) What is the entropy change when 900 ©ª is added to 12 mol of ethylene initially at 210 « , at atmospheric pressure? Assume ethylene can be modeled as an ideal gas with ¦-dependent § ¨ . Problem 40 ( Smith, van Ness, Abbot, 5.29, page 195 – modified) A device with no moving parts takes as input compressed air at 25 « and pressure...
