WebIn volumetric analysis, the reagent of a known concentration (titrant) is mixed with the unknown solution (analyte) until the reaction between them is just complete. The point at which the reaction is complete is called the endpoint. The volume of titrant required to reach the endpoint is a measure of the analyte’s concentration. Webfluid flowing through a cross‐section per unit time is called the volumetric flow, V°: V V dA VA (m3/s) A n The mass and volume flow rate are related by: m°=ρV°= V°/ v. Conservation of Energy For control volumes, an additional mechanism can change the energy of …
