Document Summary
Ap physics 2 dc circuits: consider a system designed to force a steady flow of water through a pipe. A schematic of the proposed system is shown in figure 1: note the following: a. ) Energy is provided to the system by a water pump. Water at low pressure enters the pump"s intake port, has work done on it, and leaves the output port at higher pressure. All fluids move from high pressure to low pressure; the pressurized output water moves clockwise toward the low pressure side of the system. b. ) In some cases it is useful to know how much water passes a particular point in the circuit per unit time. This is called the flowrate; its units are in gallons per second. Note: flow-rate should not be confused with rate of change quantities like acceleration. Flow-rate does not measure how far the flow travels per unit time (velocity).
