Discharge Coefficients of Chamfered Orifices and Nozzles: An account of a series of experiments carried out in order to determine the effect of chamfer on the variation of discharge co‐efficient

REFERENCE has frequently been made to the increase in the discharge coefficient of chamfered orifices and nozzles, yet few investigations have been made to study these variations in detail. The experiments described in the following were carried out in an attempt to clear some of these points.
