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 two-phase mixture. Compute the pressure drop as a function of flow rate within this range. Using property look- up and equation-solving software and analytical integration (as in the in-class example) will be required. Use the McAdams correlation for single-phase liquid computations and the HEM (with f TP = f lo ) for friction. There is no significant acceleration pressure drop in the single-phase region; ignore) for friction....
