Abstract : A meter for measuring the particle velocity of underwater shock waves is discussed. Field test apparatus used to position and orient the meter underwater is also discussed. To evaluate the meter, measurements of water particle velocity produced by shock waves from tapered and compact charges are compared with computations of velocity based on pressure measurements. It is shown that the independent measurement of water particle velocity provides a check on the calibration of the piezoelectric gages used to measure pressure. Uses of the water particle velocity meter in applications where computations of particle velocity are unreliable are also discussed. (Author)
