Generated explanation

The illustration compares five factors affecting water supply, with more water shown on the left and less water on the right. Pipe cross-sections contrast larger and smaller diameters and smooth versus irregular interior surfaces. Pipe runs contrast fewer changes in direction with a more circuitous route containing additional elbows. Arrows represent higher and lower supply pressure, while open-ended vertical pipes compare lower and higher discharge elevations. The diagram indicates that larger, smoother pipes, fewer bends, higher pressure, and lower discharge height favor greater water flow.
