Water hammer is the shock caused by the sudden decrease in velocity of a flowing fluid and the time it takes for the pressure wave for round trip travel in the pipe. The Joukowski impulse equation is used to

Weirs – Open Channel Flow Rate Measurement Weirs can be used to measure flow rates in open channels and rivers – common for water supply and sewage plants

A properly sized water heater will meet your household’s hot water needs while operating more efficiently. Therefore, before purchasing a water …

To determine streamflow, water scientists take continuous measurements of a stream’s stage height and periodic measurements of discharge. The relationship between this data, which they visualize using a graph and best-fit curve, represents streamflow.

A specific formula determines the correct water supply line size. Information such as a fixture count determines that water volume is sufficient.

Turbulent Flow Basics. In a mold cooling system Turbulent water flow is much more efficient at removing heat than laminar flow. After turbulent flow is achieved, increasing the flow rate further yields more cooling benefit, but at a declining rate compared to water flow rate.

A water clock or clepsydra (Greek κλεψύδρα from κλέπτειν kleptein, ‘to steal’; ὕδωρ hydor, ‘water’) is any timepiece in which time is measured by the regulated flow of liquid into (inflow type) or out from (outflow type) a vessel where the amount is then measured.
