    This class was tough.

    Course Overview:

    Great course for problem-solving minds. It covers the basics in Chemical Engineering: units, pressure calculations, mass balances, and energy balances within chemical processes. By the end of this course, you should know for sure whether you're interested in Chemical Engineering as a career.

    Course highlights:

    The course starts out going over basic unit conversions and simple calculations, such as differential pressure across manometers. It then dives deeper into mass balances (always remember: what goes in must come out--don't overthink it). Then the course ends up in energy balances, which are a tad trickier, but as long as you start with the generic formula that he gives you, you should be good to go.

    Hours per week:

    9-11 hours

    Advice for students:

    A big thing to keep in mind about this course is that practice problems are essential. Merely following along in lecture and thinking, "Oh that makes sense," will not get you anywhere on the exams. Practice every problem he does in class and every homework problem several times before each exam. What's more--do the practice problems without using his notes as a guide. Trying them completely by yourself will prove to you whether or not you're prepared for the exams.

    This class was tough.

    Course Overview:

    It is a required course for all chemical engineering students at VT, but I would recommend taking it because of Dr. Durrill himself. He is an excellent instructor, advisor, and teacher.

    Course highlights:

    The highlight for me was learning about the chemical processes. It was also extremely rewarding to challenge myself and learn in a new way.

    Hours per week:

    9-11 hours

    Advice for students:

    Attend Dr. Durrill's office hours.

    Not too easy. Not too difficult.

    Course Overview:

    This is the absolute best course you will take at Virginia Tech hands down. The tests are all fair and you will get out of the course what you put into it. Every other chemical engineering class is based off of this one so once you understand it all your other classes are not that bad. Preston Durrill gives lots of practical examples to learn from so you have an application for everything that you learn in the course.

    Course highlights:

    Finally realizing that at the end of the day everything is literally [accumulation] = [in] - [out]. Recognizing how this principle guides everything in this course and many others was absolutely incredible.

    Hours per week:

    6-8 hours

    Advice for students:

    Learn as you go through the course and do not wait to understand a topic. Once you understand how to apply balances to problems, the amount of time you spend on homework dramatically reduces and study time also does. Remember that in this class you will get whatever you put in, so don't ever feel discouraged just work more and ask for more resources (Durrill will give them to you if you ask!)
