Unformatted text preview: Department of Chemical Engineering ChE 110A University of California, Santa Barbara Winter 2011 Problem Set No. 6 Due: Wednesday, February 16, 2011 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 dense, nonideal gas passes through a heat exchanger. Can you use the expression Δg G ¡ ¢£ ¤ ¥¦ ¤ §¦ ¨ ¤ ©¦ ª¨ «¬¦ for this process if (a) the pressure drops substantially, and (b) the pressure stays the same? Explain your answer. Problem 26 ( Smith, van Ness, Abbott, 4.1b, page 150) For steady flow in a heat exchanger at approximately atmospheric pressure, what is the heat transferred when 14 ®¯° propane is heated from 250 to 1200 ± ? Problem 27 ( Smith, van Ness, Abbot, 4.2c, page 150) For steady flow through a heat exchanger at approximately atmospheric pressure, what is the...
