Flow in Pipes

Caratteristiche generali del flusso del tubo I
Caratteristiche generali del flusso del tubo I
Pipe flow describes fluid movement through enclosed, fully-filled conduits, typically cylindrical pipes like water pipes or hydraulic hoses, engineered to ...
Caratteristiche generali del flusso di tubi II
Caratteristiche generali del flusso di tubi II
As fluid enters a pipe, it first flows through an entrance region where the velocity profile adjusts, forming a boundary layer along the walls. This ...
Flusso laminare
Flusso laminare
Laminar flow refers to the smooth, orderly motion of fluid particles in which each particle follows parallel paths with minimal mixing between layers. The ...
Flusso laminare: risoluzione dei problemi
Flusso laminare: risoluzione dei problemi
Consider air flowing through the pipe at 300 Kelvin at standard atmospheric pressure, with a mass flowrate of 0.0163 kilograms per second. If the flow is ...
Flusso turbolento
Flusso turbolento
Turbulent flow is a fluid movement marked by chaotic shifts in pressure and velocity. Unlike laminar flow, turbulent flow displays complex, irregular ...
Flusso turbolento: risoluzione dei problemi
Flusso turbolento: risoluzione dei problemi
Consider a liquid that needs to be carbonated. Both the liquid and the carbon dioxide gas are cooled. The temperature is selected as 20 degrees Celsius to ...
Gravi perdite nei tubi
Gravi perdite nei tubi
Consider  a fluid flowing through a pipe; it encounters frictional resistance, causing energy losses known as major losses, resulting in a pressure ...
Perdite minori nei tubi
Perdite minori nei tubi
Minor losses in pipe systems arise from components like valves, bends, and fittings that disrupt fluid flow, causing energy dissipation through turbulence ...
Sistemi a tubo singolo
Sistemi a tubo singolo
In pipe flow problems, scenarios are grouped by known information and desired calculation and are typically classified as Type I, II, or III. In a Type I ...
Sistemi di tubazioni multiple
Sistemi di tubazioni multiple
Multiple pipe systems consist of interconnected pipes that regulate fluid flow across complex networks. They can be arranged in series, parallel, loop, or ...
Misurazione della portata del tubo
Misurazione della portata del tubo
Flow measurement devices—such as orifice, nozzle, and Venturimeters—operate by narrowing the flow area. This increases fluid velocity and ...
Misurazione della portata dei tubi: risoluzione dei problemi
Misurazione della portata dei tubi: risoluzione dei problemi
Consider a spray tank system designed to evenly apply pest-control liquid to plants. The system includes a pressurized tank at 150 kPa filled with ...
Esempio di progettazione: Progettazione di un impianto idraulico residenziale
Esempio di progettazione: Progettazione di un impianto idraulico residenziale
The residential plumbing system is designed by assessing the building's water demand and flow rate needs based on occupancy and fixture requirements. ...
