10.302 Fall 2004 Exam 3 Wednesday, December 1, 2004 1. (60 points) A pure liquid is available from storage at its boiling point of 100 ° C. The material is to be fed to a reactor as a vapor at 200 ° C. The heating is to be achieved by using saturated high pressure steam at 230 ° C. Subcooling of the condensate will not be practiced. Relevant properties of the flow stream and of the steam are given below. The flow rate of the feed stream is 10kg/s. A. What is the minimum flow rate of steam that can accomplish this task in an infinitely large, true counter-current exchanger? In an infinitely large true co-current exchanger? B. Subject to the following assumptions, determine the area required for a true counter- current exchanger. The tube wall is very thin so the inside and outside areas are essentially equal. (i) On the feed stream side of the tubes, h = 1000 W/m 2 K when the feed stream liquid is in contact with the tubes; (ii) On the feed stream side of the tubes, h = 300 W/ m 2
