Transient and Frequency response consideration — Lesson 1

This lesson covers the concept of dynamic response considerations in fluid flow analysis. It delves into the importance of understanding the transient and frequency response characteristics of a system, especially when measuring flow parameters such as pressure. The lesson explains how the system's response to changes in pressure can affect the accuracy of measurements. It also discusses the factors that influence the system's natural frequency and damping ratio, such as the length and radius of the tube used in the measurement system. The lesson further explores the impact of signal attenuation on the system's output.
