Give the Inlet and Outlet Valves for Controlling a Compressor

Question

A compressor has one degree of freedom more than a pump because the fluid is compressible instead of incompressible. So for a pump we can use one independent variable and set up a feedback control loop using any of the following dependent variables: flow rate (either outlet or inlet, they are the same), inlet pressure or outlet pressure. Assume that you want to control a compressor using control valves on both the inlet and outlet lines. Using the standard ISA symbols, draw two viable feedback control loops, one for each control valve on the following diagram.


 
Summary

The question belongs to Mechanical Engineering and the question is about drawing inlet and outlet valves for a compressor for controlling compressor. The symbols have been drawn with standard ISA symbols.

    Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
