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.

Assignment 10, Question 4, Problem Book #202
Problem Statement
An ideal Brayton cycle with a two-stage compressor, a two-stage turbine, and a regenerator
operates with a mass flow rate of 25 kg/s. The regenerator cold inlet is at 490 K and its
effectiveness is 60%. Ambient conditions are 90 kPa and 20°C. The intercooler operates at
450 kPa and the reheater operates at 550 kPa. The temperature at the exit of the combustion
chamber is 1,400 K. Heat is removed in the intercooler at a rate of 2.5 MW and heat is added
in the reheater at a rate of 10 MW. Determine the thermal efficiency and the back work
ratio. Use a cold air standard analysis with cp = 1.005 kJ/(kg K) and k = 1.4.

Assignment 10, Question 3, Problem Book #198
Problem Statement
Consider a Brayton cycle with a regenerator. The regenerator has an effectiveness of 75%.
The compressor inlet conditions are 1.2 bar and 300 K and the mass flowrate is 4.5 kg/s. The
compressor outlet pressure is 9 bar. Both the compressor and turbine consist of a single
isentropic stage. What minimum power output must be achieved before the regenerator
begins to have a benefit? Use an air-standard analysis.
