ank or reservoir R in figure 30 is connected with a supply pipe 60 ELECTRICITY AND MAGNETISM AB. The pressure along the pipe is indicated by the height of thewater in the tubes C, D, and E. When the pipe is closed at B, the level is the same in R, C,D, and E; this is calledthe static condition.But… … Fig. a30. B x Hydraulic resistance causes drop inpressure. due to friction against the walls of the pipe through which the waterhas to run. Problems 1. Three wires of 2, 6, and 8 ohms resistance are connected in seriesbetween the terminals of a battery which maintains 4 volts pressurewhen so…
