Flow in pipes - Pipe Flow Calculations

Flow in pipes is considered to be laminar if Reynolds number is less than 2320, and turbulent if the Reynolds number is greater than 4000. Between these two values is "critical" zone where the flow can be laminar or turbulent or in the process of change and is mainly unpredictable.Heat Pipe Technology | Boyd CorporationThe heat pipe working fluid chosen depends on the operating temperature range of the application. Working fluids range from liquid helium for extremely low temperature applications (-271°C) to silver (>2,000°C) for extremely high temperatures. The most common heat pipe working fluid is water for an operating temperature range from 1°C to 325°C.How Fluid Flows in Pipes Accendo ReliabilityThe more viscous, or less slippery, a fluid the harder it is to get shearing between layers. The high viscosity prevents rapid velocity changes occurring between layers. The sub layer in viscous fluids is thicker than in low viscosity fluids. Velocity Effects. At low speeds the whole flow across a pipe is laminar and the fluid slides over itself.

What Temperature Range for PVC Pipe? | Hunker

Standardized reference points for all published PVC dimensions usually apply to a temperature of 73 degrees F. Colder temperatures typically do not affect PVC piping's strength, but as PVC piping gets warmer, it becomes more pliable and less able to hold pressurized fluid. The precise upper temperature limit can vary slightly depending on the exact specifications of the PVC pipe.Working Fluids and Temperature Ranges of Heat PipesThe amount of heat that can be transferred for cryogenic heat pipes is quite low due to the small heats of vaporization, high viscosities, and small surface tensions of the working fluids. Low Temperature Range. The low temperature range is from 200 to 550 K. Most heat pipe applications fall within this range.
