The analysis of a stationary, rotationally symmetric liquid jet which leads to an expression for the average normal stress at the exit of a capillary tube is reexamined with particular attention to the effect of surface tension. The limiting case of a nearly cylindrical jet is compared with the analysis presented by Gavis and Middleman.
