Optimum Adjustment of Installation System of Hydraulic Ram

This study was aimed to optimize the ratio of length of inwater pipe and water head， the results show that when the ratio is 4∶1～6∶1， the installation material and the expenditure can be reduced and the capacity of dilivery water by hydraulic ram can also be increased． The relationships among capacity of dilivery water， length of inwater pipe and water level at different water level was also given．
