Over 100 questionnaires asking about field experience@ design standards@ and attitudes on the effect of pipe reactions on centrifugal pumps were received from the Power and Process industries. This survey@ which was prompted by industry inquiries@ examines the experience and needs of piping and pump system designers@ manufacturers@ and operators. It was designed to help PVRC determine whether a significant pump-piping interaction problem exists and to what extent; and also to help set research priorities and provide guidance to Code and Standards bodies.
