principles of pressure Flashcards
1st principle of pressure
perpendicular to any surface on which it acts
2nd principle of pressure
fluid at rest is same intensity in all direction
3rd principle of pressure
confined fluid is transmitted equally in all directions
4th principle of pressure
proportional to its depths
5th principle of pressure
proportional to the density of the liquid
6th principle of pressure
independent of the vessel
1st principle of friction loss
Varies with the length of hose or pipe
2nd principle of friction loss
Varies with the square of the increase in velocity of the flow
3rd principle of friction loss
Varies inversely as the fifth power of the diameter
4th principle of friction loss
The same regardless of the pressure on the water
