The model is developed and the boundary condition is approximated at the lower boundary of the channel. It is shown that a hydrophobic surface can significantly reduce the hydraulic resistance due to the occurrence of bubble layer. Moreover, at the slip ratio equal to 1 mm, the water flow rate in the channel with the height of 1 mm increases by 2.5 times.
