Chapter 31, Problem 1R
What is the purpose of a pressure regulator?
Expert Solution & Answer
To determine
The purpose of the pressure regulator.
Answer to Problem 1R
The purpose of the pressure regulator is reducing the high system pressure or cylinder pressure to the lower working pressure.
Explanation of Solution
The main purpose of all the pressure regulators is to reduce the high system pressure or cylinder pressure to the lower working pressure.
The pressure regulator is an instrument that is used to control the pressure of the liquids or gases by reducing the input pressure to a controlled required output pressure. It is important to all the pressure regulators to keep the lower pressure constant over the range of the flow rates. There are different types of the pressure regulator. All these regulators work on the same principle. There is a limitation to these regulators that they cannot be used in the place of each other or cannot be interchanged with each other in any operation due to their specific design for the specific purpose.
Conclusion:
The purpose of the pressure regulator is reducing the high system pressure or cylinder pressure to the lower working pressure.
