Jet thrusts and pressure drops of several kinds of liquids issuing through small orifices were measured and compared with the predictions from numerical analyses of the Navier-Stokes equations. Reasonable agreements for so-called Newtonian fluids were obtained between the experimental and predicted thrusts and pressure drops for orifices with openings of the order of 1OOμm size, but the experimental results were found to be below the predictions for orifices of the order of 1Oμm. It was suggested that water and glycerol solutions have an elastic property for elongational flows passing through small orifices.
