Course Description

Welcome to the Transient State Mass Balance Course!

I designed this course is for general engineering fields. Chemical and Process Engineers will find it very relevant for their study curriculum but even Mechanical or Industrial Engineers will find it very interesting!

By the end of this course you will learn:

  • Basic Theory of Steady and Transient State
  • How to account for the Accumulation of a System
  • Identify Transient State Processes
  • Model Transient State Processes with and without Chemical Reactions
  • An insight on how to model Transient State with Software

By the end of the Course you will be able to:

  • Solve Mass Balance Problems of many real-life Chemical Processes
  • Solve many Transient State problems in engineering

The course is structured as follow:

  • 3 Sections of Theory and Applied Examples (Video-Based!)
  • 9 Mass Balance Solved Exercises (Put the theory into practice!)
  • 2 Quizes for Learning Review
  • Support on the Discussion Board!

This is a very important Subject in Engineering and is the basis of further courses such as:

  • Energy Balance and Thermodynamic
  • Heat and Mass Transfer Operations and Unit Operations
  • Reactor Engineering and Plant Design

I teach this course for about $400 per semester. You will get it as low as $15 for a LIFETIME!

Take the course and you will have a greater advantage than your classmates to get a better grade on your university courses!

Remember that this is only ONE block of ALL the MASS BALANCE courses! Check out my other courses in Udemy!

The Course Curriculum may be seen below!

What are the requirements?

  • Basic Math operations
  • First Order Differential Equations
  • Basics on Mass Balance (see other courses)

What am I going to get from this course?

Section 2: Problem Solving in Transient State

Introduciton to Problem Solving Section


An example of a Transient State


A second example of a Transient State


How we could solve a Software Problem


A tank is going to be filled with Phosphoric Acid. This is a transient state operatoins since the quantity of matter changes with respect of time

Exercise#2 - Air Filled Tank

Filling a tank in unsteady state. Be sure to account for the accumulation term.


A leak of a gas in a lab. Calculate the time required to increase the concentration of such material


A leak of a gas in a lab. Calculate the time required to increase the concentration of such material


A Salt filled tank. Process is in transient state


How to increase the concentration of Oxygen to a tank


An overview on Reactor Engineering - Operation of a Batch Reactor


This is a very typical process for enzymes. They react in batches, therefore is transient state


An absorber will decrease the concentration of CO2 to a stream.

Final Conclusion and Notes on the Course


Hey there!

Thank you very much for joining the course! Be sure to leave a review... It REALLY help us all... Specially the Udemy Community. you think this course is worth the time and money? Why not leave it in a review? You think is not worth it, its not well explained? Why not leave that as well?

Thank you in advance guys and good luck studying all these engineering subjects!

Instructor Biography

Emmanuel Ortega, Passionate Engineer... I love teaching Online to the World!

I'm a Chemical Engineer!

I've been in the Chemical Industry for about 3 years. I love applying all my knowledge learned in University to the Daily Engineering Life. From working in a Petrochemical Plant as a Process Plant Designer to working with textile material from Polyester Yarns; I could teach you a lot of how it is important to learn the Engineering subjects!

My expertise:

  • Chemical Process Design
  • Plant Design
  • Heat Transfer Operations and Equipment Design
  • Industrial Polyester Yarn
  • Online Tutoring

Right now I'm preparing online material for Engineers all over the world. I have a dream in which online education will break all barriers and let Engineers all over the world learn easier and faster! Please join me in my quest!

The Courses I design are entirely dynamic. You will see theory and then apply it ASAP to a real life problem! I even use the books you are using right now in your engineering courses...

Hope to see you in any of the Courses I'm offering!
