Karl Geiger, Eric Gruber, Ritchie King, Per Wimmercranz ENGS 34, W06 Professor Richter 2/14/06 Experiment B – Frictional Flow Through Pipes (Internal Flows) Laboratory Purpose : The purpose of this lab exercise was to determine various properties of flow through a pipe. A dye injector created a visualization of flow through a plexiglass pipe and presented an illustration of the different flow phases (Laminar, transition, and turbulent). Adjusting the flow rates allowed for a determination of the range of flows that created the different phases by using the dye as a visual aid. The laboratory exercises also illustrated the principle that pressure drops are created along the length of the pipes due to frictional losses (which are affected by roughness and are a function of velocity). One other important determination in the laboratory was the effect of surface roughness on frictional head losses. This was accomplished by looking at flow losses through a corroded (very rough) pipe. The relationship is illustrated by the Moody Chart which relates surface roughness curves to frictional coefficients and the Reynolds Number. Finally, the characteristics of pipe flows in parallel were determined by looking at pressure drops and flow rates in two different pipes. Results: The data obtained during the experiment and the calculated results are contained on the following pages.
