| Abstract: | A differential equation for aerated jet motion developed based on the application of gravity, buoyancy and resistanceis presented here which is solved then by Runge,Kutta method. At last,the calculated value of jet trajectory length was compared with the prototype measure value, their maximum relative error is about 3.4%. |
