Abstract
Theoretical equations for unsteady, compressible, laminar flow in cylindrical tubing were derived for pressure measuring systems comprised of up to three tube sizes connected to constant volume transducers. The basic equations were solved for both step and ramp pressure input forcing functions. Digital computer programs were written to be used as engineering tools for rapid determination of system characteristics. Examples of the ability of the programs to compare tubing systems, optimize diameters, generate time responses to synthesized forcing functions, and determine lag times, distortion, and attenuation are presented as guides for prospective users of the programs.Keywords
