Unformatted text preview: hart to noncircular ducts using an equivalent duct “diameter.” The addition of minor losses due to valves, elbows, fittings, and other devices is presented in the form of loss coefficients to be incorporated along with Moody-type friction losses. Multiple-pipe systems are discussed briefly and are seen to be quite complex algebraically and appropriate for computer solution. Diffusers are added to ducts to increase pressure recovery at the exit of a system. Their behavior is presented as experimental data, since the theory of real diffusers is still not well developed. The chapter ends with a discussion of flowmeters, especially the pitot-static tube and the Bernoulli-obstruction type of meter. Flowmeters also require careful experimental calibration. | e-Text Main Menu | Textbook Table of Contents | Study Guide Problems 405 Problems P6.4 Most of the problems herein are fairly straightforward.
