Pumping Apparatus Driver/Operator Handbook Flashcards
For a given flow velocity, friction loss is approximately the same, regardless of the pressure on the water
Fouth Principle of Friction Loss
For the same discharge friction loss varies inversely as the 5th power of the diameter of the hose
Third Principle of Friction Loss
When hoses are the same size, friction loss varies approximately with the square of the increase in the velocity of the flow
Second Principle of Friction Loss
If all other conditions are the same, friction loss varies directly with the length of the hose or pipe
First Principle of Friction Loss
The pressure of a liquid on the bottom of a vessel is independent of the shape of the vessel
Sixth Principle of Fluid Pressure
The pressure of a liquid in an open vessel is proportional to the density of the liquid
Fifth Principle of Fluid Pressure
The pressure of a liquid in an open vessel is proportional to its depth
Fourth Principle of Fluid Pressure
Pressure applied to a confined fluid from without its transmitted equally in all directions
Third Principle of Fluid pressure
Fluid pressure at a point in a fluid at rest is the same intensity in all directions
Second Principle of Fluid Pressure
Fluid pressure is perpendicular to any surface on which it acts
