Priciples Of Friction Loss

Question 1

When hose are the same size, friction loss varies approximately with the square of the increase in the velocity of the flow.

Answer 1

2nd principle

Question 2

For the same discharge ,friction loss varies inversely as the fifth power of the diameter of the hose.

Answer 2

3rd principle

Question 3

For a given flow velocity,friction loss is approximately the same,regardless of the pressure on water.

Answer 3

4th principle

Question 4

If all other conditions are the same, friction loss varies directly with the length of the hose or pipe.

Answer 4

1st principle
