Unformatted text preview: Department of Chemical Engineering ChE 110A University of California, Santa Barbara Winter 2010 Problem Set No. 6 Due: Wednesday, February 17, 2010 Objective : To understand and perform thermodynamic calculations involving sensible heats, latent heats, and heats of chemical reaction. Note: Numerical values for some problems have been changed from those in the book. Problem 25 ( thought problem) A stream of liquid water at g G 25 with molar flowrate enters a boiler. When the stream exits the heat exchanger, its quality is 70%, meaning that 70% of the stream is saturated vapor and 30% is saturated liquid. If the entire process occurs near atmospheric pressure, how would you solve for the rate of heat that must be added, , given the information above? Outline your answer using equations and defining variables as necessary. Problem 26 ( Smith, van Ness, Abbott, 4.45-4.46d, page 157) Carbon dioxide is heated in a steady-flow process at atmospheric pressure, using a heat exchanger. exchanger....
