| The characteristics of a two-dimensional jet through a symmetric slot in a gravity field are considered here as an extension of a gravity-free problem. The coefficient of discharge $C_d$ is found to be $C_d~0.61102(1£«0.31857$varepsilon$^2)$ in terms of a small parameter $varepsilon$. The shape of jet is derived and computed correctly up to first order. |
