摘要：
The paper presents the results of the hydraulic resistance coefficient measurements at the inlet of microchannel. The Reynolds number ranged from 900 to 2300. The channel with inlet diameter of 3.5 mm is abruptly narrowed to a diameter of 0.9 mm. We measured the pressure drop in the area of sharp change in diameter. Measured hydraulic resistance coefficient was compared with the previously obtained coefficients for microchannels of the same geometry. It is shown that for the studied interconnected channel geometry no differences were found between micro and minichannels.
