ME 130L Experimental Fluid Mechanics Spring 2007 Lab #5 - Flow in Pipes -- Background and Prelab Calculations Objectives: 1. Observe transition from laminar to fully turbulent flow in a pipe and experimentally define the conditions for transition. 2. Measure pressure drop in a pipe and express in dimensionless form (friction factor). 3. Correlate measured friction factor to Reynolds number and compare with published data. Background: Piping systems (see Figure 1) are vital for countless real world applications. Flow and pressure drop in piping systems is one of the most important practical applications of fluid mechanics in mechanical engineering. "Head losses" must be made up by a pump or blower; to specify what size pump or blower is needed for a given flow rate, therefore, requires that these losses be predicted with some accuracy. In this lab you will make direct measurements of the pressure losses in a pipe flow system, and compare these measurements with predicted pressure losses.
