Description

Hi, I'm Kaamil the Chemical Engineer.I currently work as a Process Engineer in a multinational petrochemicals company. It is one of the largest companies by market cap on the Johannesburg Stock Exchange. Many of the concepts you will read about in your textbooks, I have seen with my own two eyes. So, I would like to share these experiences with you. I hope that my stories will make your first year of Engineering a bit less abstract.Chemical Engineers are lauded worldwide for their problem-solving abilities, and that is exactly what I want you to learn from this course. Once you have these skills, you can apply them to Investing, Engineering, Business and more.We will cover a range of examples, all of which require an innovative approach and a sharp mind. Sections covered include: unit conversions, dimensional analysis, mass and mole fractions, densities and bulk densities, specific volume and specific gravity, the ideal gas law, molar mass of a gas mixture, flowrates in pipelines, mixing operations, and more.You can use the examples to teach yourself, and then use the test questions to evaluate your problem-solving skills.This should set you on your way to becoming a great Engineer!
