Learn About the Acceleration Head and How To Model It

The pistons, or diaphragm of a reciprocating (positive displacement) pump causes a cyclical variation, typically in some sinusoidal form, of both flow in pressure in a piping system. The magnitude varies, depending on the type and design of the pump. What is acceleration head? Acceleration head is the energy required to change the velocity of the liquid in the system from an at rest, or zero condition, to some non-zero value. To help us understand acceleration head a little more clearly, you could compare it to a race car. In a drag race, the race car will accelerate to some maximum velocity,...

How a Russian Hydraulics Handbook Gained the Respect of the American Nuclear Industry

We are all shaped by our experiences as engineers. Our early experiences as young engineers are especially influential. 

I first worked in the aerospace industry for five years and then the nuclear industry for two years. At each of these companies we relied heavily on a handbook written originally in Russian by a Russian engineer. I am talking about the Handbook of Hydraulic Resistance by I.E. Idelchik. This book is my "go to" book on any unusual pipe system configuration hydraulic calculations and, especially, with calculations at tees and wyes.

What is Pogo and Why On Earth Would Anyone Want To Suppress It?

The time was almost 30 years ago and it is fair to say I was not quite out of the "still wet behind the ears" stage for an engineer. I had been working in industry for about three years and I was just given a project that would change my career direction and, in fact, my life. The project? I was assigned to evaluate a new concept Pogo suppressor on a cryogenic rocket engine liquid oxygen (LOX) feedline.
