TO-22-C055 - Measurement Methods and Techniques for Pressure Losses of Pipe Fittings

Pressure losses of pipe fittings are important design information for sizing pipelines and selecting pumps. Currently, there is no standard method of test for determining the pressure loss of pipe fittings. To assist future development of a standard method of test, this paper provides an overview of measurement methods and techniques for determining the pressure loss of pipe fittings. Principles as well as the advantages and disadvantages of each existing method are discussed. Instrumentation techniques are illustrated in detail, including guidelines and recommendations for the design or selection of pressure taps, impulse lines, pressure transducers, and flow meters. Finally, future research requirements and objectives for standardizing existing test methods are identified.
