Note (General): The maximum head rise in the pipe line system with two valves, one at the outlet end and the other at the center of the pipe line, is lower than that produced by closing the outlet valve only when the closing speeds of the valves are the same. The reason is explained using the classical waterhammer theory. The waterhammer equations, which include the friction term, are solved by the method of characteristics. Charts are presented for determining the maximum head fluctuation in the pipe line system with two valves which close simultaneously at the same constant speed. These charts include the cases with steady state friction losses of 30, 50 and 80％ of the reservoir head, and with no friction loss.
