Triangular V-notch weirs are a fundamental tool in hydraulic engineering, providing a cost-effective and reliable method for measuring flow in open channels. Accurate flow measurement is essential for managing water resources, monitoring the environment, and conducting hydraulic research. These weirs operate on the principle that the flow rate is related to the opening angle of […]
An orifice meter is a flow measuring device that is very popular among other flow measuring instruments due to its design simplicity, cost efficiency and easy manufacturability to determine the discharge in single and multi-phase flow. This section will focus on the structure of an orifice meter and calculation method of coefficient of discharge of
If you have observed cigarette smoke, you may have noticed that it initially rises as a smooth, steady plume before beginning to fluctuate erratically as it moves upward. Similar behavior occurs with other plumes. This phenomenon mirrors observations in pipe flow: at low velocities, the flow is smooth and orderly, but above a certain critical
The fundamental conservation laws—such as the conservation of mass and the first law of thermodynamics—are formulated for a fixed-identity collection of matter, known as a closed system in thermodynamics. However, analyzing a control volume (or open system) is often more practical. This requires converting those fundamental laws into forms applicable to the control volume perspective. A direct analogy exists
