Abstract We investigate the deionized water flows in microtubes made of quartz at high pressure under steady flow condition in situations that (i) pure nitrogen is used as the pressure source, and the experimental pressure is 0.1--1 MPa; (ii) the inner diameters of the experimental microtubes are from 6μm to 50μm. The results indicate that (i) the flow characteristics of the microtubes with inner diameters of 50μm, 20μm, 15μm, 10μm agree well with the traditional macro flow mechanics, (ii) there are obvious warps as compared with theoretical values in 6μm microtubes.
