|---|---|---|
| Radius | 1.5 Times the Diameter of the Pipe | Equal to the pipe diameter |
| Characteristics | Smoother flow and lower pressure drop | More Frequent Direction Changes |
| Space | Needs More Spaace Because of the Greater Bend Radius. | Because of the Tighter Curve, More Space is Saved. |
