Table of contents


Pumps and motors are essential in many applications. However, they are often neglected, wrongly sized and overlooked on the efficiency. With an inefficient pumping system, you will be wasting precious energy every day!
In the first two topics, I will go through the fundamentals first, right from fluid mechanic theories such as Bernoulli and Energy Equation, and how to relate the theories to real life application. You will also learn how to plot the system curve, interpret a pump curve and size a suitable pump for your application.
In the next two topics, you will learn how to calculate motor input power, motor output power, motor efficiency, interpret the motor name plate and finally size a motor for a particular pump application. You will also learn how to determine and optimize the whole motor driven system.
Please join me in this exciting journey and i hope to see you soon!

Practitioner and Trainer for Building Engineers
Hello! I graduated with a masters in mechanical engineering and I started off my career as a Heating Ventilation and Air-Conditioning engineer.
As a HVAC engineer, my job is to do the design and equipment selection for the water side and air side of the air conditioning system, such as chillers, cooling towers, pumps and piping. The air side includes air handling unit, fan coil unit and ducting system.
After years of experience, I decided to move on to a Building Management System company as an application engineer. It is one of the best decision I have made in my career life as I got to learn so much about the trade through this role, which I have never thought of as a HVAC designer. I got to master the controls of HVAC within a building, and specialized in optimizing HVAC system performance for energy savings.
And now, I provide consultancy services and training workshops to building owners and facility managers. I equip them with the knowledge on how to reduce their building energy consumption significantly through the air conditioning system. With my new found passion in teaching, knowledge sharing and online course creation, I hope to reach out to more people who are interested in my area of expertise globally!
