High head pressure

Using the drag flow, pressure flow, and actual output, a measure of the metering-section fill can be obtained: Fill Length = [QP/ (QD-QA)]L. Where: QP = Pressure flow. QD = Drag flow. QA = Actual output. L = Length of metering section. The amount of fill necessary to prevent a cyclic surge of this type depends on the polymer viscosity, channel ....

Provide simple measurement instructions. Water head pressure at a specific location is simply determined by the height (or depth) of the water above that location.
