THERMODYNAMICS - THEORY A control volume may involve one or more forms of work at the same time. If the boundary of the control volume is stationary‚ the moving boundary work is zero‚ and the work terms involved are shaft work and electric work. Another work form with the fluid is flow work.

Hard engineering refers to the construction of physical structures to defend against erosive power of waves To protect a coast from erosion‚ people have built seawalls in front of a cliff or along the coast. A seawall is usually made of concrete. It acts as a buffer and absorbs energy of breaking waves especially during storms where the waves are strong‚ thus protecting the coast. A seawall shields and protects the coast from the direct impact of the incoming waves‚ thus reducing erosion. However

close look at my Resume will indicate that I majored in the exploitation of oil and gas fields in my undergraduate program and specialized in petroleum engineering‚ a similar specialty‚ in my Master’s program. It may well be asked why I maintain such a close affinity with petroleum. The answer is simple and straightforward—because I was born and I grew up on an oil field and I have cherished a deep love for all that it represent. Even as a child‚ I had a habit of watching for hours how beam-pumping

Chapter 6 Momentum Analysis of Flow Systems Chapter 6 MOMENTUM ANALYSIS OF FLOW SYSTEMS Newton’s Laws and Conservation of Momentum 6-1C Newton’s first law states that “a body at rest remains at rest‚ and a body in motion remains in motion at the same velocity in a straight path when the net force acting on it is zero.” Therefore‚ a body tends to preserve its state or inertia. Newton’s second law states that “the acceleration of a body is proportional to the net force acting on it and is inversely
