What are the 5 majority causes of failures (after flexibility analysis) of a system?

What are the effects of excessive flexibility?

Excessive flexibility causes an increase in material costs, pressure drops, and loss of pump efficiency.

What are the methods of incorporating flexibility in a piping arrangement?

Using flexible piping with bends and turns, use of expansion loops between fixed locations, or use of expansion joints between ...Continue Reading

What is the purpose of flexibility analysis?

Flexibility analysis assures that there is not any overstress or fatigue, leakage at joints or distortions are piping connections or ...Continue Reading

What is the objective of having flexibility within a piping system?

To produce neither excessive stress within the configuration and limit excessive end reaction at the piping terminal.

What are some applications for a piping system?

Conventional and nuclear power plant, petroleum refinery, chemical industry, natural gas transmission, food processing and pharma industry, water and sewage ...Continue Reading

What are some adverse operating conditions of a piping system?

Fluctuating temperatures, changes in pressure, and modification in flow rate.

Why is fluid velocity controlled?

Fluid velocity is controlled to prevent operational problems such as water hammer, steam hammer, relief valve discharge loading, and vibrational ...Continue Reading

What is a two phase flow?

A two phase flow is when phases do not consist of same chemical substance.

Why do piping systems use pumps?

Piping systems use pumps to develop the pressure or head required to maintain the system design flow rates.

Why must piping system pressure drops be maintained?

Piping system pressure drops must be maintained within reasonable values to limit the installed size of the system pumps and ...Continue Reading

What is dynamic head?

Dynamic head is the equivalent height of a fluid that is to be pumped, taking into account the friction losses ...Continue Reading

What is system static head?

System static head is the internal energy of fluid due to the pressure exterted on its container.

In regards to backflow, what is back syphonage?

Back syphonage is an open system connected to a closed system and the pressure in the closed system falls below ...Continue Reading

In regards to the syphon effect, what conditions are backflow or reverseflow caused by?

In regards to backflow, what is back pressure?

Back pressure is a high pressure system cross connected with a lower pressure system where the high pressure system can ...Continue Reading

In regards to the syphon effect, what is the syphon principle?

The syphon principle is a system in which syphon principle is employed to carry water through elevated parts.

What is the first critical value of piping size criteria?

The first critical value of piping size criteria is allowable pressure drop for the entire network.

In regards to the fifth step of the hardy cross method which is to add pseudo loops what does this step entail?(

To add pseudo loops in the Hardy Cross method, you should add psuedo loops as required.

In regards to the fourth step of the hardy cross method which is to assign direction what does this step entail?

To assign direction, you should assign base direction and indicate whether to go clockwise or counterclockwise.
