Planning an experimental study of water valves

Designing the plan of the experiment represents the optimal control of empirical research while processing an incomplete knowledge of the mechanism of phenomena. Experiments are usually performed in small series according to a pre-compiled algorithm, optimal in a pre-defined range. After each series of experiments, the measurement results are processed and an informed decision is made. Statistical processing of experiment data allows us to get the correct research results with errors that do not exceed the tolerance limits. The research goal is to develop a program and plan for the experimental study of the laws and quantitative values of the hydraulic characteristics of water folding valves. As a result of the research, attention is emphasized on the preliminary processing of the experiment data provided for the design of the experiment to study the hydraulic characteristics of the valves. As a part of the research of the experiment design, a program for the experimental change in water flow through the passage opening of the water valves was developed and verified. The results of the research allow us to carry out experimental studies of the hydraulic characteristics of the valves and obtain data with a given statistical security. © Published under licence by IOP Publishing Ltd.
