CIRCUITS WITH RESISTORS, BATTERIES, AMMETERS AND VOLTMETERS ELECTRICAL …
1. CIRCUITS WITH RESISTORS, BATTERIES, AMMETERS AND VOLTMETERS For water flow in a narrow pipe, the drag force is propor-tional to the flow speed and to the pipe lengthl, i.e. k= κl. For ordinary pipes, the drag force (and hence, the coefficient κ) depends also on the diameter of the pipe.) depends also on the diameter of the pipe.
