In this video, we discuss the effect of a change in inlet pressure on centrifugal compressors performance.
This video is part of our online course: Understand and predict your centrifugal compressor performance and behavior.
Centrifugal compressors are highly sensitive to the gas operating conditions at their inlet. Operating parameters such as pressure, temperature, compressibility, molecular weight and specific heat ratio of the gas as well as the compressor’s rotational speed strongly affect the performance of these machines.
This training course will show you how to use the performance curves and a set of equations to calculate the effects of changes in these operating parameters. This will give you the necessary tools and place you in a better position to understand, evaluate and predict your compressor performance and behavior for a successful operation of your plant and piping system.
The training course is designed around a series of practical examples which we work through to a solution to reinforce your understanding of this complex topic.
Also included in this training course a valuable Excel Workbook : Centrifugal Compressor Performance Excel Workbook
This workbook provides qualitative and quick comparisons and application notes for centrifugal compressors. It describes calculations and procedures to predict performance characteristics, especially head, discharge pressure and power.

HOE PRESSURE RATIO REMAINS CONSTANT.. EVEN IF SUCTION PRESSURE CHANGES
This is wrong, The discharge pressure remains constant, the diff pressure increases there by reduction in volumetric flow resulting in reduced power consumption.
