In this work, pressure loss is simulated analytically in a convergent nozzle. The inlet vector velocity has two components in axial and tangential directions. The governing equations of the turbulence flow are solved by integration method to obtain pressure loss along the nozzle wall.The results show that the boundary layer thickness depends only on the nozzle angles, Reynolds number and Roseby number. It is also found that pressure distribution decreases drastically near the outlet of the nozzle about 100 percent in average in different conditions. The maximum value of the boundary layer thickness is about three times of the outlet thickness.
