Unformatted text preview: ENU 4134 – Homework Assignment #2 – Fall 2011 – D. Schubring 1 ENU 4134 – Homework Assignment #2 – Fall 2011 DUE: Friday, September 16 ALLOWED COLLABORATION: This assignment may be completed in groups of up to 3, who may all turn in one paper. WARNING: This is not a problem to start the night before it is due. Liquid water at 20 ◦ C flows into the bottom of a 0.01 m diameter tube, 4.5 m in length. The heat flux around the tube, q 00 is 1.2 MW m 2 . Provided the flow rate is within a certain range (0.065 to 0.20 kg s 1 ), the water will boil on its way up and exit as a twophase mixture. Compute the pressure drop as a function of flow rate within this range. Using property look up and equationsolving software and analytical integration (as in the inclass example) will be required. Use the McAdams correlation for singlephase liquid computations and the HEM (with f TP = f lo ) for friction. There is no significant acceleration pressure drop in the singlephase region; ignore) for friction....
