Confident body language while standing and walking

Having strong, confident, excellent body language isn’t just about having good posture for posture’s sake, or making your mother happy. Non-verbal cues are important: people instinctually use them to size up your attitude, personality, and state-of-being. If you currently walk around bent over, or constantly looking down, or hunching against yourself, it can communicate things you may not want. Some people do this to make themselves look smaller, like very tall or very shy people.

The “proper” way to walk around, we are often taught* is back straight, chin up, eyes forward, chest out slightly, smile on your face.

*This advice is intended for any secular business or social setting in North America. Your situation may vary.

However, just being told to stand up straight doesn’t really cut it. To help, I share two “metaphors” that you can visualize in your mind to help you adopt good posture. Pick one:

Controlling Equipment Articles by Walter Driedger

Want to design an equipment’s control scheme, draw up the P&ID, determine what process variables to control and when, and understand why you’re doing it?

Check out this excellent set of articles:

Controlling Equipment Articles by Walter Driedger

In language that’s understandable and at the right level of detail, you will get some solid advice on how to design the basic control strategy for:

  • Centrifugal Pumps
  • Positive Displacement Pumps
  • Shell and tube heat exchangers
  • Steam heaters
  • Fired hears
  • Process Vessels and Tanks
  • Plus some engineering humour!

This is not about buying the equipment, nor about tuning process models, this is laying out the basic strategy of what to measure and what to control. It is fundamental to designing the “nervous system” of any process.

This is a difficult topic to find practical advice on: there is very little explanation or “how-to” of control philosophies that I’ve found, in magazines, books for professionals, university courses, etc. So I recommend you read these articles if you are learning about P&IDs or control schemes.

Another option if you have cash to spend is the Instrument Engineers’ Handbook Volume Two by Bela G. Liptak et. al. It has some specific advice on controlling many, many different kinds of equipment. However, be warned: this book is geared to instrumentation engineers and has a different focus, and very instrumentation-driven details. Unless you are heavily into instrumentation, I would try to borrow a copy and give it a quick read before deciding to buy it.

Updates to posts, comment policy

For clarity, I revised some grammar and added sentences to many posts. In particular I added some explanation to make Determine Pressure Drop in Straight Pipe and Microsoft Visio Guidelines, Tricks, Keyboard Shortcuts easier to read. Nothing factual has changed, so I don’t think you need to re-read them if you understood the first time.

I also added some more info about printing articles and making comments in the about page.

Microsoft Visio Guidelines, Tricks, Keyboard Shortcuts

Ever have to use Microsoft Visio? Lets learn some guidelines to help you draw shapes and connectors more easily, some useful tricks to set up drawings the way you want, and keyboard shortcuts to work more quickly.

Microsoft Visio is a relatively simple piece of software. It doesn’t have the bells and whistles of a hard-core graphics program or drafting program. However, it is quite easy to pick up and learn, works like a Microsoft Office product, and is excellent at making shapes like boxes and connecting them. This makes Visio great for things like organization charts, or website design wireframes. It means it can also work for flowsheet drawings like Process Block Diagrams, Process Flow Diagrams or even Piping and Instrumentation Diagrams if you want to push your luck: you make the shapes of equipment, valves, etc. and connect them with lines representing pipes.

Temperature Rise Due to Slapping

On the lighter side of thermodynamics, here’s a cute example problem from a thermo textbook: Temperature Rise Due to Slapping

I like the bit about acting in a “professional manner.”
