Rotary Valves: An Introduction to Selection and Use
Rotary Valves are compact devices widely used in bulk handling systems to control the discharge of powders and granular solids, normally under gravity, between two parts of a system; usually when there is a gas pressure differential between the two parts. By definition, in their basic construction - ignoring any drive, they are the simplest of machines each incorporating just one moving element; a multi-vane rotor.

Types of Flow Meters
Flow is defined as the rate (volume or area per unit time) at which a substance travels through a given cross section and is characterized at specific temperatures and pressures. The instruments used to measure flow are termed flow meters. The main components of a flow meter include the sensor, signal processor and transmitter. Flow sensors use acoustic waves and electromagnetic fields to measure the flow through a given area via physical quantities, such as acceleration, frequency, pressure and volume. As a result, many flow meters are named with respect to the physical property that helps to measure the flow.

Water Hammer: Joukowsky Equation
Joukowsky's overpressure, also known as the Joukowsky shock or water hammer, is a phenomenon that occurs in fluid dynamics when there is a sudden change in the flow velocity of a liquid within a pipeline, typically due to rapid valve closure or pump shutdown.
