In a chemical process industry, equipments are represented using mathematical equations. These are generally differential equation of order first, second and so on. This course discusses the dynamics of these mathematical models with respect to different changes. Topics discussed will be a part of PROCESS DYNAMICS AND CONTROL subject which is an integral part of GATE Chemical Engineering syllabus.

Crack GATE Chemical Engineering for 2019 to get into PSUs, Government Jobs & M.Tech. at IITs. Get great courses along with previous year question papers, answer keys & syllabus by great educators.

Course Outline

The answer to the need to study the process dynamics and control has been discussed.

Necessity to Study the Dynamics and Control of a Process

What is meant by a mathematical model and why it is needed? Every such topic is discussed here.

Process Modelling

Step input forcing function with it's daily life examples have been discussed.

Step Input Function

The other 3 types of forcing functions i.e. rectangular pulse, unit pulse and impulse functions have been discussed.

Rectangular Pulse, Unit Pulse and Impulse Input Function

Basics of ramp input and sinusoidal input forcing functions have been discussed.

Ramp Input and Sinusoidal Input Function

Complete discussion on first order system with the determination of it's transfer function and meaning of each term has been done.

First Order Systems

How does the first order systems respond towards step change and what does steady state gain means? All such questions have been discussed in this lesson.

Step Input Response of the First Order Systems

It is very interesting to know that how first order systems respond to the Linear or Ramp changes.

Impulse and Ramp Input Response of First Order Systems

First order system when disturbed by a Sinusoidal change respond with a lag.

Sinusoidal Input Response of a First Order System

Tank system is the most easy example to be considered for first order systems.

Example of First Order Process: Tank System

Four cases have been discussed for tank system based on different values of time constant and steady state gain.

Physical Explanation of Tank System

Non Linear resistance make it difficult for the system to be represented in terms of deviation variables.

Tank System with Non-linear Resistance

Mercury thermometer is a self regulating system and is an example of first order systems.

Mercury Thermometer

Purely Capacitive Systems are a special case of first order systems.

Purely Capacitive System

Tutorial-1

Transfer function of second order systems has been evaluated with it's step change response.

Second Order Systems

Damped Vibrator is an excellent example of second order systems.

Damped Vibrator: Example of Second Order System

A complete discussion on underdamped response is done and terms like overshoot, decay ratio , etc have been defined.

Underdamped Response-Part 1

Response time, rise time have been discussed with numerical problems.

Underdamped Response-Part2

A complete discussion on non interacting systems has been done here.

MultiCapacity Systems-Part 1

The interacting systems always show an overdamped response. A complete discussion on interacting systems is done here.

In this course we’d be covering almost all the basics of colloidal chemistry, like classification, preparation, properties, applications etc of colloids.
How colloids play a vital role in our daily life. 
Hope this course would be useful to you.
Cheers!
