The energy system simulation is often used for the conservation of energy calculation. There is the one ..characteristic type of pump.. to express the polynomial to calculate the transportation power in such a system, too. This is good for can the selection of the equipment, and to make the characteristic type again when the capacity of the equipment is changed, it becomes annoying work. Then, it is possible to calculate selecting neither the manufacturer nor the equipment to calculate the transportation power easily, and the standard characteristic type of the small, general-purpose eddy pump is made.
