Energy Equation - Pressure Loss vs. Head Loss

WebMar 30, 2024 · The head loss in a fluid system is typically calculated using the Darcy-Weisbach equation, which relates the head loss to the fluid's velocity, the pipe's diameter and the friction factor. The Darcy-Weisbach equation is expressed thusly: hL = f (L/D) (V^2/2g) Where: "hL" is the head loss. "f" is the friction factor "L" is the length of the pipe. WebJul 17, 2024 · The head loss thus increases (approximately) quadratically with the volume flow rate. “Approximately” because the friction factor is in turn influenced by the volume flow rate. The figure below shows … WebHead-loss form.

WebHead loss curve. Head loss curve is used to describe the head loss through a General purpose valve as a function of flow rate. It provides the capability to model devices and situations with unique head loss – flow relationships such as reduced flow- backflow prevention valves, turbines, and so on. Time Patterns WebAn example discharge curve is shown for an 8-inch (in) venturi meter on figure 14-1. Thus, the meters may serve as reliable flow measuring devices. ... This feature causes a greater amount of turbulent expansion head loss than the loss that occurs in venturi meters, which suppress exit turbulence with a gradually expanding tube boundary. ...

WebDarcy–Weisbach equation. In fluid dynamics, the Darcy–Weisbach equation is an empirical equation that relates the head loss, or pressure loss, due to friction along a given length of pipe to the average velocity of the fluid flow for an incompressible fluid. The equation is named after Henry Darcy and Julius Weisbach. WebHead loss in a pumping system increases with increasing flow through the system, and can be shown graphically as a system head curve like that in Fig. 6-15.The system head …
