Beschreibung
Zusammenfassung:	A flow velocity determining apparatus (10) according to the present invention includes an irradiating unit (20) that emits irradiation light (L1) toward a liquid mixture (BL) which contains a non-spherical solid (BC) and a liquid (BP) and flows through a flow path (TB), a detecting unit (30) that detects reflected light (L2) emitted by the irradiating unit (20) and reflected by the liquid mixture (BL) flowing through the flow path (TB), the detecting unit (32) being disposed on at least one side of an optical axis (L2A) of the reflected light (L2) when seen in a plan view of an imaginary plane including an optical axis (L1A) of the irradiation light (L1) and the optical axis (L2A) of the reflected light (L2), and a determining unit (40) that determines a flow velocity of the liquid mixture (BL) by using a light amount of the reflected light (L2) detected by the detecting unit (32).
