Orifice Meter: Definition, Construction, Working, Experiment, Derivation, Formula, Advantages, Application [Notes & PDF]

An orifice meter consists of a 100 mm diameter orifice in a 250 mm diameter pipe and has a discharge coefficient of 0.65 . The pipe conveys oil of relative density 0.9 and the pressure difference between the sides of the orifice plate is measured by a mercury U-tube manometer which shows a reading of 760 mm . Calculate the volume flow rate in the pipeline. | Numerade
