1. How to Prevent Condensation-Induced Water Hammer.

Author

Czyszczewski, Michael F.

Subjects
*WATER hammer, *PIPE flow, *OPEN-channel flow, *STRATIFIED flow, *COMPRESSIBLE flow, *TRANSITION flow, *WATER power, *ANNULAR flow
Abstract

The article focuses on the causes and types of Condensation-induced water hammer (CIWH) and mentions prevention of CIWH through estimating velocities and involved pressure. Topics discussed include creation of vapor pockets while isolated steam by pipe geometry during system shutdown or refill, velocity formed by surface waves than the liquid, and generation of pressure pulse of water hammer.

2. Checklist for matching air cylinders to load requirements.

Author

HITCHCOX, ALAN L.

Subjects
*HYDRAULIC cylinders, *GUIDELINES, *INTERNAL friction, *PISTONS, *ANNULAR flow
Abstract

The article focuses on simple guidelines which can be used to determine the right hydraulic cylinder to fit their specific needs. It mentions that the internal friction which is produced by piston and rod seals prevents a cylinder from achieving the theoretical output force. The significance of considering the annular area, determining the actual operating pressure, and determining the speed requirements.
