PROBLEM TO BE SOLVED: To fix various conditions including a nozzle and a diffuser pipe of a pump for objectively satisfying a request item regardless of an intuition and an experience. SOLUTION: Precise nozzle pressure, a nozzle diameter and an inner diameter of the diffusion pipe are calculated to a kind, a physical property, a suction quantity, a suction side actual head, a suction side distance, a delivery side actual head and a delivery side distance of an object required at work. The suction quantity corresponding to the whole resistance is calculated from the linear relationship between the head and the suction quantity by deducing the head and the suction quantity being two elements required for performance of an ejector from a publicly known calculation expression of a conventional jet pump or the ejector.
