Abstract : The purpose of this program was to experimentally determine the transient hydraulic pressure loads and pressure losses in simple piping systems and elements caused by transient loads. Transient pressure loads were applied either to the pipe proper or directly to the fluid within the pipe. A cursory analysis and computational comparison of the experimental data was made and it was determined that the data can be employed to evaluate the prediction capabilities of present day computer methods. The basic pipe elements tested included straight pipes, area changes, elbows, valves, a pump, and surge tanks. The piping system tested was a closed loop system which contained the following elements: elbows, straight pipes, valves, a pump, and an orifice flow measuring element. Measurements made during the experiments included pipe displacement and velocity, transient and steady state hydraulic pressure measurements, and in some cases, pipe strain. (Author)
