Jump shot parameters selected to determine movement pattern included kinematic analysis of a number of variables around the ankle, knee, hip, trunk, shoulder, elbow, and wrist joints and the following variables determined: (a) temporal series of joint angular displacement and velocities; (b) minimum and maximum joint angular displacements; (c) joint range of motion (d) joint angle at ball release; (e) minimum and maximum joint angular velocities; and, (f) movement duration.
Its volumetric efficiency used most in the field to determine the condition of a hydraulic pump - based on its increase in internal leakage through wear or damage. But without reference to theoretical flow, the actual flow measured by the flow meter would be meaningless.
To figure out how many hours you need to run your pump, you need to know how fast your pump works. You will need to find the gpm or gallons per minute of water that your pump circulates. You can find this out one of two ways: by either looking in your manual that came with the pump or by calling the manufacturer.
