Hydraulic transients in a short horizontal pipeline resulting from the closure of a valve at the upstream end of the pipe were examined. Test conditions resulted in water column separation at the valve. Measurements of transient pressure and velocity changes for a number of tests are presented. Calculated results based on the method of characteristics are compared with the measurements. Special attention was devoted to the evaluation of the dynamic behavior of the valve.
