Some pumps used for 1000 hours, the ship propeller in the use of time is also greatly reduced because of the efficiency of air piping.
某些水泵使用1000小时左右即出现严重的空蚀，船舶螺旋桨在使用一段时间后也因空蚀而效率大大降低。
Agreement between the numerical results of reduced velocity around an open-water propeller and the measurements is satisfactory.
敞水螺旋桨的脉动速度计算结果与试验结果吻合良好。
After the vortex distribution is solved according to the boundary condition of no-flow-penetrating through the blade surface, the velocity reduced by the propeller can be calculated.
