ME 130L 17910 – 17975 The University of Texas at Austin Mechanical Engineering Department Fall ’10 Dr. Hidrovo 1 ME 130L Experimental Fluid Mechanics Pre-Lab #5 - Flow in PipesI.Background Read Sections 8.1 through 8.4 in Munson, Young, Okiishi, and Huebsch to gain exposure to the ideas of laminar-turbulent transition, head losses, and the friction factor. Pay particular attention to Section 8.1 (General Characteristics of Pipe Flow) and Section 8.4 Dimensional Analysis of Pipe Flow). Before coming to this lab, work out the following calculations. II.Analysis (8 points) Before coming to this lab, work out the following calculations. 1.You will be observing laminar-turbulent transition for room temperature (about 20°C) water flowing in a 3/4" ID pipe. Estimate the flow rate in gpm at which transition should begin (for a critical ReD≈ 2300) and the flow rate in gpm for fully turbulent flow (ReD> 4000). Repeat your calculations for a 5/8" ID pipe. 2.The circular pipe for which you will measure head loss is a 3/4" ID (actual inside diameter is
