Abstract
Pressure transients occurring in both uniform-and series-pipeline is analytically investigated. An input signal to the line system is considered to be given by a waveform of single, pulse, which is realized by the change in the pressure or flow rate at the sending-end. Each responses olution for these pressure inputs and flow rates is derived under the pipe-end condition of open-end and closed-end. The fundamental equation used in this analysis is the one for the fluid line model in which the frequency-dependent effect of viscosity is taken into consideration. R esponse curvesa re calculated to represent the behavior of pulse wave along with the increase in both the time and axial pipe coordinates. It is clarified that the pulser esponsesa re very helpful to get physical understanding of the wave properties like distortion, reflection and transmission.
