2 main reasons for reduction in frictional pressure |
Frictional loss in hose The effects of gravity working above the water source or pump |
|
|
4 factors affecting factors of pressure loss |
Internal diameter of hose Output flow of water Height in meter above/below water source Length of hose line |
|
|
Laws of frictional loss |
1 - the pressure loss is directly proportional to the length of the hose through which water flows 2 - if the flowmrate is double the pressure loss is increased by 4 times 3 - pressure loss is inversely proportionate to the hose diameter |
|
