Abstract
A state analysis device is capable of determining a state of the interior of piping with high precision, and includes: an index calculation means for deriving an index indicating the state of the piping, based on a flow speed of fluid flowing out of the piping, and a fluid pressure of the interior of the piping at two or more locations of the piping; and a determination means for determining the state of the piping, based on the index.
