velocity tests, were applied for investigetion of velocity measurement of
drilling fluid from drilling bit jets. PIV enables planar measurement of
the flow profile while LDV enables one-point measurement only. Jet
velocities on various distances from nozzle were measured and hydraulic
horsepowers and impact forces for the same distances were calculated. Keywords: drilling bit nozzle,jet velocity,PIV,LDV,pressure distribution
