This paper deals with the mathematical modelling of the amplitudę frequency characteristic of pressure at a pipeline with fluid and with the experimental verification of this modelling for the pipeline with Iow viscous fluid - water. The linearized mathematical model solves the nonstationary flow in a pipeline with the continuously distributed parameters. There is supposed a viscous compressible fluid in an elastic pipeline. There is used the method of Laplace transformation for the solution of the system of differential equations.
