| Abstract: | Based on hydraulics theories and concept of loss-of-head, a new calculative formula of loss-of-head on taper nozzle was deducted. The results show that the new calculative formula was very satisfied with data of experimentation, and the average value of relative errors is only 7. 12%. So the calculative formula has widely applicability. |
